On the other hand (since we're complementing each other's ideas), with Yavon's 
idea, it's easy to have puzzle N+1 depend on the solution to puzzle N.  That 
may limit (to some small extent) the advantage that a highly parallel system 
would have in solving puzzles - while parallelism might be able to speed any 
individual puzzle, they would still have to solve the sequence of puzzles 
sequentially.
