IPV6 to the rescue.
Every network behind a NAT router should set up a 6to4 tunnel,
probably some time early in 2003.
IPv6 is almost source code compatible with IPv4, so every
application should soon be recompiled to be IPv6 compatible.
Every computer with a recent operating system, for example recent
linux kernels and windows XP, theoretically supports IPv6.
So if your P2P application is IPv6 compatible, you can get a semi
permanent IPv6 IP automatically from a server, and thereafter do
peer to peer, just as if you were full, no kidding, on the
internet.
IPv6 is being driven largely by demands for peer to peer. Phone
companies want to give each cell phone an IP address (being done
already in Japan). Businesses want to videoconference.
