Better yet, send them large PGP-encrypted messages using maximum-length public keys that are not registered with the key servers. That should keep their Crays busy for a while. :-)

Hey, I can encrypt /vmunix with a random key as fast as the next person. :) -- Ed Carp, N7EKG erc@apple.com 510/659-9560 anon-0001@khijol.uucp If you want magic, let go of your armor.
