Sounds like we should form a "DES Breaker's Club".

In case it isn't obvious, I should point out that before trying to
solve the system of Boolean equations, it is advisable to boil down
the scope of the problem by finding and exploiting structure in
the encryption system.  There are some good opportunities to apply
a bit of (abstract) algebra to this problem.  (The simpler the
eventual system of equations that needs to be solved
computationally, the better off you are.)
