right.  very sad, but very true.

ietf said don't do nat in v4.  the market said screw you.  the market won, and
ietf ended up having to add nat support into various protocols, and started
having nat oriented working groups, and so on.  i expect the same with nat v6.
don't let ietf scare you -- they're really just you, or will be once they're
up s**t creek without your paddle.  (again.)

as of today, we have ip with bigger addresses, and so we have the ability to
explode the global routing table at faster than light speeds.  with ipv4 we
had to make due with sublight speeds.  wheee, warp drive.  yay.

i have more confidence in the ability of router vendors to bend moore's law
and in backbone architects and routing protocol architects to bend graph
theory, than i have for example in diesel-from-algae as a way to solve the
world's carbon problem.  so i'm not nec'ily hopeful, but i'm more hopeless
about other things than i am about a 2M-route DFZ.
