Hmm ... that's where fpga enhanced machines can change the balance point,
especially if external to the PC and separately powered. A 4 watt FPGA
appliance, if not solar powered, would cost about a quarter ($0.25) per
month to operate, and reasonably kickout between 20 to 300 trillion keys
per month. At which point, RC5 becomes more attractive than playing the
lotto :)
