It's an idea, but I don't think we'd be successful. Bovine has
already done about 28% of the keyspace and has enough horsepower
signed up to do about .5% a day right now. If you check out the
top 100 email stats you will see they have some really big guns:
the top team yesterday, averaged 272943.56
kkeys/sec! That is 272943560 keys/sec! My P100 can do something
like 140kkeys/sec max... So unless we get _alot_ of computers
signed up here, I think it's better to take our chances with
the Bovine effort.

The future has arrived; it's just not evenly distributed.
