Should this policy automatically expire once a certain number of prefixes
are assigned, after a certain period of time, when 32-bit ASNs are deployed,
etc. or can we reasonably expect operators to force repealing the policy if
a "land rush" develops?

I had to read this several times to understand you weren't expecting end
sites to become LIRs; please consider separating end sites and small ISPs
into different paragraphs.

I don't like the wording here, but I can't seem to come up with something

24 months seems excessive for end-site renumbering since they won't have to
coordinate with sub-assignees.  Perhaps different limits for allocations and

Other comments:

Should prefixes be required to be taken from block(s) designated for this
use, since that will help ISPs adjust their filters?  This seems common with
other recent proposals.

Should multiple organizations using the same ASN be considered a single
end-site and thus required to share a prefix?

Should having PI space disqualify an end-site from PA assignments, or vice
versa?  What about PI space allocated under other policies?

Should we include any way for disconnected sites (which many not have an
ASN) to get PI space?  The IPv4 policy directs such sites to use RFC 1918
space, but there is no equivalent (yet) in IPv6.

In another forum it was claimed that ARIN charged ISPs $100/yr for IPv6 PI
allocations; looking at the fee schedule, it appears that starting 1 Jan 05,
the fees will be $2,500 plus $2,250/yr for a /32.  Anyone requesting a
second allocation pays $20k plus $18k/yr.  That's quite a difference from

ARIN's "usual and customary way" has already set the fees for end-user
direct assignments to be the same as for ISP allocations, per section 12(D)
of the 3 Aug 04 BoT meeting.

At these fee levels, I must question the viability of direct PI assignments
as a replacement for many or even most potential ULA uses, which I
understand to be a central motivation for this policy proposal.  Of course,
this policy is still warranted for "normal" uses of PI space in IPv6.
