Fairness. Free trade is and must be a two-way street. Don't have that
if we let someone pay lip service to free trade and then act as a
proxy for a third party who's gaming the system.

The nice thing about my way is that ARIN need never make that call. It
need only warn registrants and then let them make the call.

The only rough spot is that *if* we continue some form of needs
analysis we'd have to deliberately cut it off at the /24 level so that
you can't transfer anything smaller than a /24 unless you qualify for
the /24. Personally, with the free pool gone I'm disinclined to
continue needs-based analysis, at least on the relatively small
transfers like /22 or /24.

But you asked which things we wanted to put on the table as candidate
requirements for transfers, not the ones we wanted to argue against.
I'm trying to respect that.
