I agree - much better if you don't have NAT.
I'm not qualified to discuss the best way to accelerate the advantages that
the Internet brings to everyone's lives while simultaneously encouraging
people to move to IPv6. But if the powers-that-be wish there to be a VoIP
solution that supports people who, through no fault of their own, find
themselves behind NAT (ie: at hotels, etc.), then we're happy to provide the
solution. If not, then at least we might all benefit from the resulting
debate.

NAT traversal....????
http://www.spectrum.ieee.org/select/1098/int.html
NATs are a no-no
HEATH: I was going to say that IEEE Spectrum should make it very clear that
this group's consensus would appear to be: let's
discourage NATs--I mean the manufacture of them at all--because there is a
real need for IPv6.
HUITEMA: It's more than that. There is a real need for security and you
can't have security with NATs.
CERF: NAT is a guaranteed spoofing box in effect.

Subject: RE: [Sip] Eating our own Dog Food...could the IAB and IESG use SIP
for conference calls
Agreed. To enable access from behind firewalls (ie: homes, hotels,
conferences, airports, Asia, ...), we can donate a B2BUA-based NAT traversal
solution for SIP (same one that Pulver's Free World Dialup uses). It sits
near the proxy, with nothing needed on the client end.
Bottom line: In addition to helping the IESG and IAB, it will help SIP to
have more IETF participants gaining experience with it.

That's great idea. We can help with our free SIP server (www.iptel.org/ser/)
and hosting the services.
