As tempting as it is to continue discussing how a geographic addressing plan 
would work in practice, it is clear that the current Internet topology and 
transit/peering model do not support such a plan at this time and it would 
take years (and probably regulatory pressure) to make it happen.

In that light, it appears necessary to provide PI prefixes in the immediate 
future, and we should be debating the current proposal in comparison to the 
proposed alternatives (none) and to doing nothing.  If/when a viable 
alternative is developed, ARIN can modify or repeal the PI policy based on 
community discussion.  Unlike v4 swamp assignments, ARIN also has clear 
authority to reclaim _all_ v6 assignments if necessary.

Today, there are about 16k origin-only ASes; that is the number of new IPv6 
routes that one would expect this policy to generate and is clearly within 
the capabilities of today's hardware.  If demand is significantly stronger 
than expected, the community can revisit whether it is necessary to modify 
or repeal the policy to address operational concerns even if no viable 
alternative has presented itself yet.
