Gosh, folks, but I'm afraid that I subscribe to the position that this
is precisely why the U. S. Government LIKES the DES, and doesn't
particularly care for derivative or more exceptional schemes.  That
is, the only people who really have the $$$ to break the DES
are...guess who...Aye, you've got it!! The U. S. Government!!  And if
someone comes up with a truly difficult scheme--one where pure CPU
power doesn't suffice--I firmly believe that they'll be quashed so
fast it'll make your Rotor spin.  More than 256 times, too.
