PI vs PA Address Space

The user community should not be forced into flash cuts, and the
providers can make the needed overlap period of time work for bounded
time frames.

At a minimum, the model needs to be /18+E (E==entropy due to customer
migrations).

Then, if we are going to get into implementation details now, the list
should figure out just how long that "needed overlap period" is, since
if I remember correctly, PST's original note on this indicated annual
reductions in the mask value. Right Paul?
