the point is that current policy only allocates to organizations who
commit to assigning space to other organizations and perhaps a case could
be made for a limited number of large organizations to qualify for a PI
block of IPv6 addresses.  the trick is finding the criteria which can
reach consensus as "fair" but not "too complicated".  such a policy would
encourage IPv6 adoption in these large organizations, many of whom are
unwilling to deploy it using PA addresses.

see also my reply to Michael Dillon.  there is a legitimate fairness
argument about trying to find policies that work into the future rather
than policies that need to be made more restrictive later. We've already
done that and prefer to make different mistakes this time.  it's harder!
there is no question that the easy way out is just give everyone the
equivalent (or more :-) than they currently have in IPv4.  that will work
for now and some time into the future.  sure.  but why not design a future
that is built to scale reliably?

it's really time to try to get rid of the IPv4 mindset!!  there will have
to be new and better ways of solving how to use multiple providers than
everybody's route going into the global routing table.  some work is being
done now and it's good to keep pointing out the need for creative and
scaleable solutions.  let's encourage the right solutions rather than
short term work-arounds...				/Lea
