Umm.. the entry level for a DES breaker is well under $250K, as the EFF
showed some time ago.  This is *WELL* within most Fortune 500 company's
budgets for industrial espionage.  Applying Moore's Law, it will be
under $100K very soon, if not already.

At that point, even things like supermarket chains might want to
buy into it.. I'm sure that Food Lion (one local chain in my area)
would *love* to get the data Kroger (another chain) has collected with their
'Kroger Plus' card (get discounts, they collect data on what you buy).
And I'm equally sure that Kroger would love to get Food Lion's data
from their 'VIP' program (same idea, different name).  Both programs had
to cost at least $250K to start chain-wide, so the management of each
chain obviously thinks their data is worth at least $250K.
