I concur. In fact, I was surprised that not a single one of the many P2P solutions presented at the recent excellent CODECON made any mention of support for IPv6, which can be easily be added to just about any P2P application, while every presenter bemoaned the fact that the existence of NAT's between nodes provided severe design and functionality constraints. The fix is not just obvious, it is downright trivial on any modern OS. --Lucky
