BitCoin has 8 decimals of precision, so the entire network could operate on just a handful of BitCoins. An attacker could never destroy them all. If deflation gets to the point where transactions of more than 10BC are unheard of, the client can just shift the decimal point over so that, for example, people with 0.01 BitCoins have 1.000 BitCents.
This movement is a useless waste of resources and thought process. If y'all are really intent on doing something with that massive amount of computing power, do something for Folding@Home, or some other BOINC process.
This thread should die here and now.
