Perhaps we should have 3 buckets. The first would be a /56, the
second a /48, and the third, a /40. Just for fun, let's call them
class C, B, and A respectively... (ironic half :-))

I doubt IPv4 will ever run out. As the unallocated pool of IPv4
becomes smaller and, as a result, RIRs policies and procedures become
even more unfair and draconian, people will either (a) migrate to
IPv6, (b) NAT themselves so they only use a couple IP addresses, or
(c) obtain the addresses they need from the black/gray market.
Assuming the market will be allowed to exist (and I'd argue it will
whether or not the RIRs accept the fact), I suspect a combination of
(b) and (c) will satisfy the needs of most folks unable/unwilling/
unmotivated to do (a).
Speaking only for myself of course, but the way things are going, in
the end I'm afraid Paul Francis's NUTSS (Nats, Uris, Tunnels, Sip,
and Stun) "architecture" will win out. I personally would prefer a
world in which there was a clear and obvious reason to migrate to end-
to-end IPv6, e.g., deployable multi-homing and/or trivial
renumbering, instead of FUD with questionable basis. However, to
date, I haven't see that reason.
