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?
