Hi! I'm looking for an answer to your questions as well, so if you do find a solution on other lists, could you please post it here as well?
Regarding the issue, your proposal wouldn't make for full-duplex as far as I understand since I don't see how the client would be able to send any data on the same connection _after_ getting connected. What are you using on the other end of the pipe (on the client)? Plain HTML? Flash? Java? Something else?
