Bookmarking this topic. We just started doing some networking projects in our class using Java (local only), and I'm really enjoying it.
Also, am I right to assume I can't use IP Address/Socket, so that I can create a server SWF and client SWF? Like, I'll run the server SWF, then send the client SWF to a friend so we could communicate through SWFs? I hope we could, seeing as how you mentioned we can use URLs. :(
Or could someone tell me what I should be using instead of this that's AS only?
