I'd hang on to it. Someone will eventually port my
Litecoin miner to it, the tricky bit will be dealing with the MCU (perhaps Luke-Jr could help out?).
Thank you for your work for the community but please don't give people false hope. With the scrypt speeds you are getting out of that we are talking so slow that you should still mine BTC with it. The point is we are talking about less then $5 a month after power (after the difficulty change this week).
