I definitely agree. I wasn't disparaging. I was simply saying you can 
make it even *more* complex with math. The fact that the program doesnt 
have to enforce the cryptography stuff is what makes *that* impressive 
to me. You can't unscramble the stuff without 3 or 9 keys due to the 
nature of the keys, not the nature of the lock, so to speak. :-)
