[ppml] Policy Proposal 2007-21: PIv6 for legacy holders with RSA and efficient use - Last Call

As the policy author, I'd like to get opinions on the wordsmithing we 
did at the meeting.  The text to be added now reads:

or demonstrate efficient utilization of all direct IPv4 assignments or allocations covered by a current ARIN RSA.

If an organization had multiple legacy assignments or allocations, and 
chose to cover just one of them under an RSA, would you read that that 
mean they'd only have to demonstrate efficient utilization of that one 
block?  Or does that verbiage accurately reflect the intent of the 
proposal, that all direct IPv4 assignments or allocations must be 
covered under an ARIN RSA and efficiently utilized?

If you have any suggestions for simple wording changes to reduce 
ambiguity, I'm all ears.  If no one has any better suggestions, and we 
think the current proposal text is ambiguous, I'm leaning towards 
something like:

or demonstrate efficient utilization and coverage under a current ARIN RSA of all direct IPv4 assignments or allocations.

I'm perfectly willing to stick with the current text, though, if people 
think it's clear and doesn't have any loopholes.


P.S. I'm also interested in how ARIN staff would interpret the current 
proposed text.
