A really short one time pad.

Actually, here are ten. 2^.5 3^.5 2^(1/3) 5^.5 5^(1/3) 7^.5 11^.5 13^.5 17^.5 Pi For that patter the nth root of any prime number. A lifetime of "pads" could be distributed in one trip. Of course this still means that you have to make the trip, and write down all of the above with a referring codeword or number. Cheap, I know. Wonder if this type of "one time pad" is as foolproof as truly randomly generated ones.
