and why will the result be different than the japanese experiment,
where *temporary* PI v4 space was given out to encourage v6 use,
and has never been returned to the pool?

what i am hearing are well-meaning but non-op v6 marketeers heavily
pushing lots'o v6 pi space, a few ops (e.g. terry) pushing "if folk
can't get pi space they won't join the internet," and the rest of
us trying to see through the smoke to find a win-win in that works
operationally for both the users and the routers.

we all think folk should get what they need.  we just have
differing perceptions of need and of mechanisms to test those
needs.
