Thanks for your excellent input here.

I seem to recall that the last time we went through the global PDP (with 
the "last /8" policy), that we had several RIRs who liked the general 
idea, but required substantial changes (namely N=1 instead of 2 or more) 
to support it.  IIRC, some RIRs passed it first with a higher value for 
N, then had to go back and pass the N=1 consensus version after that was 
what passed in the other RIRs.

I'm wondering if we couldn't do something similar here.  While I think 
some sort of policy along these lines might be beneficial (and we need 
*something* to tell the IANA what to do after IANA free pool 
exhaustion), I think that the policy as written is unworkable, for all 
the reasons outlined by others.

So, what if the ARIN AC were to go ahead and revise the policy along the 
lines of what Marla outlined earlier?  Assuming that a less restrictive 
policy is all we'll have consensus for, wouldn't that just mean that 
APNIC would have to pass the less restrictive version as well before it 
could advance to the ASO?

Thanks again,
