Has anyone just asked the 22 /8 holders mentioned above nicely if they might just like to give them back for some good publicity?  You know, US DoD migrates to IPv6 and returns X /8s for the good of the American people (assume ARIN) so that broadband might continue to grow and thrive in the land of the free?

Multiple times.

The most optimistic estimates are on the order of 4 years.

The most optimistic estimates of the return rate are on the order of 6-8 /8s (not the
100% of 22 /8s you are postulating).

The legal expenses would be extreme.

So, for $ALOT and 4 years of effort, you might get back as much as 4 months of
address space.

Next?
