They had a flurry of activity and now seem to be non responsive. It was a good idea but I wouldn't recommend buying in until they get their act together. If you want a BeagleBone based solution you are better off considering the Replicape with Redeem or a CRAMPS 2.2 with MachineKit. Both have a far more active development community. FastBot decided to keep the firmware closed source so nobody can help them. at least with the other two you have open source solutions and can check out the code if needed.
