Very cool!  Sounds like you guys have a lot of expertise in the area which could make you competitive quickly.  Not knowing much about hardware architecture I wonder how this would be scaled to higher speeds.  You mention you mostly do small quantity production so you'd probably be thinking of making more powerful more expensive rigs, as opposed to cheaper high volume ~500MH/s USB sticks?  Also, are you guys in a position to make the whole product or do you just do integrated circuits?
