Note that under the "slow start" IPv4 address allocation policies, 
small ISPs do not qualify for an initial allocation from ARIN until 
they have utilized a provider-assigned block of the minimum size
specified (based on being singly-homed or multi-homed.)  These same 
criteria now apply to receipt of an address block via transfer, so at 
regional IPv4 free pool depletion may be _very_ difficult to satisfy. 

There are a number of ways of addressing this (changing initial ISP 
allocation policy, changing dependence on allocation policies for 
transfer approvals, establishing a reserved block for new entrants,
etc.) but if left unaddressed will leave circumstances such that new 
entrants are precluded from participating in the transfer market as 
a recipient.  This is the type of outcome that is generally frowned
upon by governments for obvious reasons, and should be very carefully
considered by the community.
