There is a difference between 'taking the operators position' and deciding which battles to fight. The battle to fight here is to maintain the ability to exchange peer-to-peer audio and video conferencing streams. That is a battle that I beleive can be won given the right marketting approach.

Since you are the one that is routinely taking the operator's position, why should we allow punching holes in the IETF nat when that will never happen in a real ISP? No ISP is going to trust their customer base to modify the configuration of their infrastructure, so whatever the IETF experiment ends up being has to mimic that reality. The only exception I would make is to route the audio streams around the nat so people that can't attend are not completely cut off. Other than that, if you are there you are living the future. IPv6 plus multiple layers of IPv4-nat, with trust boundary issues included. Tony
