Certainly ARIN has prevented an organization from getting additional space
if their currently held space is under utilized (even if it is legacy

ARIN certainly has used a slow start model, rather than giving potentially
overly large allocations / assignments when there is not a good foundation
of a year's worth of growth to justify the size block requested.

These two practices help to sustain IPv4.

The application need based justification to transfers is an attempt
to continue these sustainable practices.

It sounds like whatever concerns people have about the depletion
of the free pool, can also be applied to the depletion of sufficiently
large blocks of IPv4 available at a reasonable / affordable price on
the transfer market.

The only way I see out of this is if there is more that enough supply
for everyone to purchase all the addresses they need to sustain
their growth until there is wide spread IPv6 adoption.

One way to encourage this is to require real IPv6 deployment along
with IPv4 transfers.  Say require 10% of the customer base to be IPv6
capable prior to approving a transfer, and require a plan to get 40%
of the customer base IPv6 capable in one year, and 80% in two years.

Choose whatever numbers seem right for the community 1%, 30%, 70%?
