[arin-ppml] ARIN-prop-137 Global Policy for post exhaustion IPv4 allocation mechanisms by the IANA

While it seemed a good idea for the last 5 /8's to be handed out equally to the 5 RIR's, for perpetual policy I'm not sure if I like equal distribution over needs-based distribution.

I support policy to address assets returned to IANA set aside for re-allocation, just not the method of equal distribution.

But if the only way to get this passed by all the RIRs is with the equal distribution clause, I would drop my objection.  I think its more important to allow IANA policy regarding
returned assets than nitpick about the re-allocation method (as long as the assets are re-allocated).

-head fuzzy from the flu, I hope I made some semblance of sense.
