I like the idea, at least on its surface. Would the reversed IP's be
for new organizations only or merely reserved for small allocations?
What do you consider small? /21, /20, /19 etc?

Perhaps you could propose a policy that would set a maximum size for a
IPv4 request and require those with needs in excess to migrate to
IPv6. The questions becomes whether the maximum size would be per
request or aggregate? As I understand it now, IPv4 will always be
available in some form but the new entrants will have to get in line
to wait for the space to become available or grease the palms of
another company wanting to "sell" their allocation.

A policy like this could keep the door open for those who need to get
in the door with IPv4 before they're able to move on to IPv6.
Personally, I would like to see a policy like this extended to those
who are technically inhibited from adopting IPv6 who have an interim
need for small IPv4 allocations and perhaps add the following to IPv4
justification requirements:

- Why IPv4 is needed vs. IPv6.
- When does the organization intend to renumber and return the IPv4 space.
- What technical limitations are preventing adoption of IPv6 between
now and the aforementioned date.

Lastly, ARIN could create a financial incentive for those who opt to
return IPv4 space or move from IPv4 to IPv6 in an expeditious fashion
which would further support a policy like the one stated above. This
could be a fee waiver credit or permanently reduced fees for those
organizations meeting certain criteria and quickly returning unneeded
IPv4 space.
