[arin-ppml] The Library Book Approach to IPv4 Scarcity

Too complex, too much hand-holding of ARIN staff.  I'd support a much  
simpler, straightforward audit and recovery of space not used.  And no  
"fees".  Any business would pay the fee and keep the space.  Recovery  
should be the failure action.
