WIth the idiotic US Government laws, you probably have a right to be.

Hmmm.  Good question.  What the program does is download a block of keys
(actually, it just gets the "start" key and explores the next 2^29 keys).
It then replys back with your OS type, e-mail address, the start key and
either a yes or a no if you found the key.  _I_ don't think this would be
prosecutable or not.  You could think of someone encoding some paragraph
with a Ceasar cipher (rotate all the letters by a certain count) and then
asking 26 people if they could check one of the rotations and reply back
either in the afirmative or the negative.

Agreed.  Noone really knows how much the US would be able to prosecute.
However, there are several companies (2.19% of total work) and a few US
government sites participating in the challenge (0.11% of the total work so
far).  I think the government would have bigger fish to fry than us little
guys!
