I do not think it's useful to spend too much energy in trying to 
figure how NATs work (or do not work).

Further, even though the draft charter talks about IPv6 and eventual
deployment, it seems to be ignoring the fact that if you use an IPv6
transition mechanism which is specifically designed to traverse NATs
(see e.g., draft-huitema-v6ops-teredo-xx [this should probably be on
the 'reading list']), you don't have these problems.

And if you are able to use a transition mechanism which is not tied to
the IP versions supported by your ISP own, the barrier for IPv6
deployment should be significantly reduced.

Therefore the issue seems to boil down to whether the NAT traversal
mechanism described in draft-huitema-v6ops-teredo-xx is sufficient to
traverse the NATs, and whether the support for something like Teredo
is expected to be sufficiently commonplace to depend on it.
