Hm...I just noticed scrolling down the hardware list that you can use it on a ps3 with CFW. It only looks like about 20MH/s but maybe now I have incentive to stop being lazy and put a CFW on my ps3 with a broken bluray drive to let this run on it...
One thing to consider... the PS3 probably pulls around 80W at least so at only 20 mhash/s I dunno if you'd break even on power costs.
