Let's say we put a price of $1 per year per IP address you want allocated 
to you. For the people really using their IP addresses according to 
current policy, this is nothing. For the people with historic allocations 
(/8 for instance), they would really have to think if it's worth $16m to 
keep that /8. Most likely scenario is that this would free up a lot of 
IPv4 address space.

If this causes migration to IPv6, well, so be it. I seriously doubt it, 
only thing I think would happen is that we would free up IPv4 space and it 
would live longer.
