Thanks, Scott, these are useful discussion points. see below

But the ARIN policy doesn't allow you to receive addresses via transfer if they think you don't qualify under current policy anyway. You have to "prequalify." See Section 8.3.2. (This I think will prove to be a fatal flaw in the policy but that goes to another question.)

At first blush this doesn't strike me as an inherently bad thing. Can you tell me what harm it does?

Another argument is that address blocks are pretty fungible, so if I get an address block from source A instead of ARIN, then ARIN has more to give out the traditional way.
