i suggest that, for most of us, there are more useful and concrete major
direct goals of ipv6 than anti-nat religion.
And in fact, the anti-NAT religion hurts deployment of IPv6
because it is hard to get customers to throw away things
they have already bought.
I would also suggest that the rapidity at which NAT is
being deployed for IPv4 suggests that we need to think about
how to deploy IPv6 in an environment where IPv4 NATs are prevalent.
Thus, it is unlikely that IPv6 will displace IPv4 NATs; tather
it will augment them.
