Well, I wouldn´t discuss this not so dramatically. We ordered one to our university for a 6 axis robot retrofit. We´re nearly complete now and it took some time. We had some trouble with the unit, but we can "move" the robot.
As all developments, that claim to be good, need a lot of time for the details, I have learned that a little bit more of it gives much more better results.
I think Bruce won´t let his device die at the moment.
On the other hand, if time really matters, just take a look around, the kindergarden is full of alternatives (Mach3, Emc2....)
