Luchs and Isilkor (I think) made the IPv6 stuff, the extension of UDP hole punching is by me. Luchs was talking about TCP hole punching, but I have doubts that that can work.
UDP hole punching is fairly simple though. You first connect to an external server to figure out the external IP and whether the NAT router changes the source port. Then you have all participants establish connections to each other at the same time to the known external IP/ports. (Conveniently, that external server can coordinate that.)
