[arin-ppml] Draft Policy 2009-1: Transfer Policy ? Revised and forwarded to the Board

Thanks for bringing this up.  As we discussed at the AC meeting, I think 
this is something that can (and should/will) be dealt with by ARIN staff 
as they implement the transfer policy.  Here's how I see it working:

Billy goes to ARIN and says "Here's a /16, please give it to Suzie."

ARIN says to Billy, "Suzie hasn't yet been approved for a /16, so you 
may want to hold on to your /16 while we process her application."

Suzie goes to ARIN and says, "I'm here for Billy's /16".  In the 
process, ARIN checks Suzie's justification, and realizes Suzie can
only justify a /18.

ARIN tell Suzie and Billy that Suzie is only approved for a /18, and 
asks Billy if he still wants to return the whole /16, or do something else.

Now that you've raised this issue, I am confident that ARIN staff will 
create operational procedures to deal with it in such a way that no one 
ends up surprised.
