Based on the results of the PPML poll, we also want to make sure the 
language covers legacy blocks, not just blocks allocated to/by ARIN.  How 
about this?  I think it would satisfy your concerns as well as the others 
raised this morning:

"The IPv4 block must be administered by ARIN, for example as part of an 
address block assigned by IANA to ARIN, or as part of a legacy address 
block allocated within the ARIN service area."

Current need justification can be very quick, when a requester provides 
all the necessary documentation in their initial request, or can take a 
little bit of back-and-forth if the requester has to go dig up 
documentation on current usage.  I'd guess that the same sort of 
timeframes would apply to a pre-qualification request, as the same 
eligibility checks would apply.

There is also the question of whether the 12-month clock has elapsed such 
that the space is eligible for transfer.

LOL.  (/me imagines people talking about transferororors and 
transfererereeeees at the L.A. meeting)  :)  The problem with the terms 
buyer and seller is the question of what's being bought and sold.  I don't 
really want to start talking about the "buyer of a set of contractual 
rights to unique registration records and associated registration 
services", or whatever the proper legal terminology would be, since you 
can't buy the numbers themselves.  :)

That's part of it.  Imagine a large company with multiple subsidiaries, 
one of which requests and receives a large block of addresses just before 
ARIN runs out.  If the other subsidiary then turns around 6 months later 
and wants to offer (different) addresses for transfer, this clause would 
require that they tell ARIN about the other subsidiaries, so that ARIN can 
consider whether their behavior, in aggregate, complies with the policy. 
In this case, it would be the transferor under 2008-2 who'd be out of line 
with the policy, hence the need for common-control disclosure there as well.
