Well, actually, I think there are 72 bit keys. Also, I don't know
exactly how they store & the keys, but they *are* tested sequentialy,
so generating them is easy. And, since, if my calculations are correct,
there are 47.2 sextillion (4.72 * 10^21) keys, they'd have to be
generated in blocks at they Main Server there at distributed.net...
