No, I am saying the deployment of LSN is likely to happen, and when it does 
an uncertain number of ip addresses may be freed up to supply the transfer

I am saying that your "proof" of the size of the transfer pool is not valid 
because you assume 100% efficiency in routed space.

Owen, any single entity is limited to a /12. I trust the ARIN staff to be 
able to determine whether the entity is a sham company, and even by the size 
of your limited pool, a /12 can't corner the market. So maybe we can at 
least temper the fear that a speculator would enter into a 4 minute market.
