You know, this was a little hard to swallow, because I consider myself to be such a clever fellow. I played around with a bunch of different schemes to derive larger pads from a password and ended up feeling like my brains were turning to mush. After spending too much time on what, in the beginning, was a simple problem, I realize I don't know jack about cryptography and should leave it in the hands of people who know what they are doing :)

Again, thanks for the advice and pointing out the correct direction to a fellow monk.
