[arin-ppml] FW: Creating a market for IPv4 address space in absence of routing table entry market

This issue (consolidation of the ISP market) is something I have been
thinking about and preparing a paper on. 

Assume for a moment, Tom, that address transfers are NOT allowed, ever,
by any RIR. 

When v4 free pool is depeleted is not the only alternative then for a
hungry ISP to acquire a smaller ISP if it wants to expand address space?

Small ISPs might be able to buy address space from larger ISPs,
especially ones that are migrating to v6. But small ISPs are much less
likely to be able to acquire larger ISPs. Usually big fish eat smaller
ones not the other way 'round.
