Hey Gang,
I'm working on a P2P chat service, and I'm deferring to y'all for some help.

I've been working away, and I've had some problem getting around firewalls and NAT (Network Address Translation) devices. Do you guys have any hints or ideas on how to accept incoming connections despite these problems? Right now I've basically been writing two clients based on whether or not someone can accept an incoming connection.

Any advice is really welcome!
