Claim 6

The method as claimed in claim 4 , wherein the logic in the programmatically generated second proxy for passing the stream data as data transmitted over a network connection creates one network connection for transmitting data between the first and second objects and a separate network connection for transmitting data between the third and fourth objects.

Claim 7

The method as claimed in claim 3 , wherein the logic in the programmatically generated second proxy for passing the stream data as data transmitted over a network connection creates a single network connection for transmitting data between the first and second objects and also for transmitting data between the third and fourth objects, and wherein the programmatically generated first proxy and a programmatically generated proxy for the fourth object further include logic for distributing the transmitted data upon receipt using multiplexing.
