When you consider that APNIC has more than 4 times the population of
the next most populous region, the fact that they have less than twice
the address space held by north america seems pretty irrelevant to the
argument. Especially when you consider that they have more than 10x
the population of North America. In fact, they have 60.8% of the population
(almost 2/3rds of the world population) and less than 1/3rd of the address
space, while North America is approximately 1/20th of the world population
and holds almost 1/5th of the address space.

The numbers above make a very good case for 2011-1 IMHO.

I think this is a red herring. If there is a continuing transfer market by
the time AfriNIC runs out, there will be addresses available to them in
that market. If there is not, then, keeping the addresses away from users
in the APNIC region will not in any way help AfriNIC at that time.

This isn't about a suicide pact. This is, however, about the damaging
consequences of asynchronous runout. Geoff Huston expresses these
much better than I can, so, I will refer you to his presentations from Busan
and Philadelphia RIR meetings.
