Robin:
If as you say there are billions of allocated or assigned addresses that
are not actually being used, wouldn't an intelligent address transfer
policy (such as Policy Proposal 2008-2) do more to facilitate more
efficient utilization of the IPv4 address space than NATs and "finer
slicing and dicing?"
