Even if we ignore the address space issues entirely, we will slide smoothly from "NATs in IPv4" to "NATs in IPv6" or, more likely, "ever more clever NATs and NAT technologies in IPv4" unless we are successful in nailing down the mechanisms to accomplish the sorts of configuration and goals in IPv6 that are causing NATs in IPv4. My sense is that we haven't done that yet. We may even be a bit behind where we thought we were 18 months ago.
The real sad thing is that many people operating enterprise or
even university networks get so used to NATs that they can't imagine to live without them anymore. They feel kind of naked
without a NAT and they will likely insist on NATs when you get
them to deploy IPv6. Fixing a mis-guided public opinion is
close to impossible.

for those who understand the pains and prefer lots of cheap global addresses. ;-)
