Hi John,
But suppose we really do have enough address space (independent of routing
issues). In that context, is site local just a shortcut to avoid dealing
with a more general problem? Should we have a address allocation policy
that updates the policies of the 70s but ignores the intermediate "we are
running out" steps? Should I be able to go to an RIR and ask for unique
space for an isolated network, justify how much of it I need, and get it
-- with no promises that the addresses can be routed (and, presumably,
without pushing a wheelbarrow full of dollars/ euros/ yen/ won/ yuan/...)?
Yes, yes and yes.
