the alleged evils of NAT, was Rate of growth on IPv6 not fast enough?
I'll preface this that I'm more of an end user then a network administrator, but I do feel I have a good enough understanding of the protocols and network administration to submit my two cents. The issue I see with this level of NAT, is the fact that I don't expect that UPNP be implemented at that level. I would see UPNP as being a security risk and prone to denial of service attacks when you have torrent clients attempting to grab every available port. Now that's going to create problems with services like Xbox Live which require UPNP to fully function since at least on one persons connection so they can "host" the game. When you're looking at player counts in the millions I'm fairly sure that they are going to be effected by CGN. That's one application I expect to see break by such large scale NAT implementations.

You are always welcome to do so.

Josh, fwiw, Not trying to hijack this thread, but please go put this over on the ARIN-discuss list. You can subscribe here: http://lists.arin.net/mailman/listinfo/arin-discuss Gaming vendors is a major outreach consideration from what I gathered from around the ARIN meeting, and it would be fantastic if you could take that discussion over there for them (and others) to see...
