[ppml] Policy Proposal: IPv4 Soft Landing

[william(at)elan.net]

I think having a policy that says that after certain time (in fact
I'd prefer it to be specified as a year rather then IPv4 depletion
thereshold), ISPs MUST demonstrate availability of IPv6 infrastructure 
before getting new ipv4 space is in fact good for IPv6 deployment
and its production use which is ultimate goal here.

I'd be interested in seeting "deploy IPv6" policy proposal that
goes along those lines (even thinking about writing one based
on some lines in David Conrad's proposal, but first want to see
where that goes).
