No doubt someone will claim you have some type of real estate interest
involved, and depending on local law, you may have rights to sit on
the IPs until lawfully evicted.
:)
But seriously I would suggest that you would have some expectation
of rights due to RFC2050 as much as any properity rights exist for
so called legacy addresses.

At any rate it sounds like a unilaterial contract change by CW,
which may be unenforcable.  I'd just continue to announce the
more specifics for 6 months just to make it as difficult as possible
for CW to re-use them.

It won't win CW and friends that's for sure. (hello AGIS/Net99, anyone?)
