uh, won't that be 14:00 CST?  as we don't do summertime here,
this difference will impact my first cuppa.

we believe in private space or we don't.  if we do, then they can
use private asns or snatch public ones and keep their 42 ribs
from mixing.  if we don't, then we have to stop whining about
giving folk real unique ip address space and asns we never see on
the public net.

we're in agreement here, though, as you know, i am more inclined
to the "you have five years to upgrade" conversion approach.  less
exposure to router code and config bugs.

but ip space is a much harder issue.  v6 did not come with a
transition plan and still has no credible one.
