[arin-ppml] Policy Proposal: Extend 16 bit ASN Assignments

[Scott Leibrand]

I disagree.  We are still waiting to get a release of the code train we 
use on the Cisco 7600 platform that supports 32-bit ASNs.  It sounds 
like they're finally getting close, but I think a further extension 
probably would be helpful.

We'll have a much better view of what's required by the fall meeting, 
when this is up for discussion.  Since that will be our last chance to 
change policy before the current 1 Jan 2010 deadline, I definitely think 
this needs to be on the agenda.
