Martin,
 
I assume you just received the DB-Net, Inc. mailing with this puzzle on
it.  It will be interesting to see how quickly everybody can solve it.
 
Last year we sent this out before the Interex show and distributed them
at the show.  We offered a prize to anybody able to solve it.  Only one
person was able to give a complete answer for all possible outcomes.
 
Good luck everyone.
