Claim 4

The method of claim 1 further comprising: detecting that the determination of which of the identified people are within a specified proximity of the user has changed as a result of any of the reports of locations; and transmitting the information indicating which of the identified people are within the specified proximity in response to the detecting.

Claim 5

The method of claim 1 further comprising receiving a user-specified proximity parameter from the mobile personal information device operated by the user and establishing the specified proximity based on the received user-specified proximity parameter.

Claim 6

The method of claim 1 further comprising disabling the transmitting of information to the user in response to a notification enabling parameter set by the user.

Claim 7

The method of claim 1 further comprising: defining for the user a plurality of groups of the identified people; designating for the user to receive the transmitted information of a subset of the groups; and excluding those of the identified people not in the designated subset from identification in the transmitted information.

Claim 8

A place-specific buddy list service system operated on at least one server computer of a distributed data communications network for access from personal data communications computers, the system comprising: a database maintaining a people/place state for a user of the service, the people/place state enumerating at least one group of people also using the service and locations of such people, wherein identifying information for each person in the at least one group is accessible by the user prior to receiving reports of the locations of the people in the at least one group, and wherein the presence of each person in the at least one group indicates previous consent by the respective person to share information with the user; a people location tracker operating responsive to received reports of the locations of the people to update the people/place state; and a first engine operating to process the people/place state to determine which of the people in the at least one group are in the user's proximity, and to generate a notification for the user having information identifying the people in the at least one group determined to be in the user's proximity.

Claim 9

A place-specific buddy list service system operated on at least one server computer of a distributed data communications network for access from personal data communications computers, the system comprising: a database maintaining a people/place state for a user of the service, the people/place state enumerating at least one group of people also using the service and locations of such people, wherein identifying information for each person in the at least one group is accessible by the user prior to receiving reports of the locations of the people in the at least one group, and wherein the presence of each person in the at least one group indicates previous consent by the respective person to share information with the user; a people location tracker operating responsive to received reports of the locations of the people to update the people/place state; and a first engine operating to process the people/place state to determine which of the people in the at least one group are in the user's proximity, and to generate a notification for the user having information identifying the people in the at least one group determined to be in the user's proximity.

Claim 10

The system of claim 7 further comprising an eventing engine operating responsive to a change in the people/place state to cause the first engine to process the determination and generate the notification.

Claim 11

The system of claim 7 further comprising a search engine operating responsive to a user-initiated search request to cause the first engine to process the determination and to generate the notification.

Claim 12

The system of claim 7 wherein the first engine determines which people are in the user's proximity and generates the notification in accordance with a set of parameters, the first engine responding to user selection of one of a plurality of user-defined modes specifying settings of the parameters to apply the parameter settings specified in the user-selected mode.

Claim 13

The system of claim 10 , wherein at least one of the plurality of user-defined modes is selected by the system based on observation of user behavior.

Claim 14

The system of claim 7 wherein the first engine determines which people are in the user's proximity and generates the notification in accordance with a set of parameters, the value of at least one of the parameters varying by place.

Claim 15

The system of claim 7 wherein the first engine determines which people are in the user's proximity and generates the notification in accordance with a set of parameters, the value of at least one of the parameters varying by time.

Claim 16

A computer-readable storage medium having stored thereon computer executable instructions for providing place-and-people based information in a data communications network having a plurality of mobile personal information devices, the instructions, when executed on at least one server of the data communications network, causing the server to: receive reports of locations of mobile personal information devices operated by a user and by people identified on a list for the user, wherein identifying information for each identified person on the list is accessible by the user prior to receiving the reports of locations, and wherein the presence of each identified person on the list indicates previous consent by the respective identified person to share information with the user; determine based at least in part on the reported locations which of the identified people on the list are within a specified proximity of the user; and transmit information indicating which of the identified people are within the specified proximity of the user to the user's mobile personal information device.

Claim 17

A computer-readable storage medium having stored thereon computer executable instructions for providing place-and-people based information in a data communications network having a plurality of mobile personal information devices, the instructions, when executed on at least one server of the data communications network, causing the server to: receive reports of locations of mobile personal information devices operated by a user and by people identified on a list for the user, wherein identifying information for each identified person on the list is accessible by the user prior to receiving the reports of locations, and wherein the presence of each identified person on the list indicates previous consent by the respective identified person to share information with the user; determine based at least in part on the reported locations which of the identified people on the list are within a specified proximity of the user; and transmit information indicating which of the identified people are within the specified proximity of the user to the user's mobile personal information device.

Claim 18

The computer-readable storage medium of claim 14 wherein the specified proximity is independent of geographic distance between the user and the identified people.

Claim 19

The computer-readable storage medium of claim 14 , wherein the instructions further cause the server to: detect that the determination of which of the identified people are within a specified proximity of the user has changed as a result of any of the reports of locations; and transmit the information indicating which of the identified people are within the specified proximity in response to the detecting.

Claim 20

The computer-readable storage medium of claim 14 , wherein the instructions further cause the server to receive a user-specified proximity parameter from the mobile personal information device operated by the user and establish the specified proximity based on the received user-specified proximity parameter.
