[WES] and from a previous mail:

[WES] No, having a registry AS# and announcing routes != having an allocation from $registry. It simply means that they are multihomed. There are plenty of networks who get PD IPv4 from one or more upstreams and announce it to all of them via BGP.
I acknowledge that multihoming with PD space in IPv6 is not necessarily attractive due to risks of your subnet announcements being filtered on some networks, but it's not impossible, nor is that germane to the discussion.

Either way, the point being made referred to cost (ARIN fees) as a barrier, not ability to get space (demonstrated need), and PD is a viable solution for at least some of the folks experiencing that financial problem. Simply handing everyone space won't change that, because if they start using it, they're still responsible for the fees.

I simply don't see the point at which this helps spur deployment. The turnaround time on processing new IPv6 address requests is not so high that pre-allocating will fundamentally save us anything, because it doesn't move the needle in terms of when it actually gets *deployed* and *used* inside of any network that currently isn't doing either. If the problem is that those who need it can't get it, propose policy to fix that. If the problem is that those who need it and want to deploy can't afford it, propose policy to fix that. This isn't a solution to either problem.
