chat application (peer to peer) without server behind firewalls

What I need is a chat application that can work even if people are behind a firewall. It would be okay for them to connect to a central server to get connection information. After that, then it needs to be able to communicate without the central server and to be able to work even if all users are behind a firewall without using port forwarding. Would need to know which protocol is being used for this. If there is a way to communicate without the central server, that would be even better (like KAZAA for example). There would be no file sharing. Just chat. This would be used as a sample for other peer to peer applications. I would like this to be in VB so I can see the code that was used (I don't have C++ at all). Let me know if you have any questions. Must work with Windows 98 and XP.
