Whoa,
Don't go getting all excited yet. The technology behind the this discussion still has a lot of variables in place that would make this impractical for our use. There is too much production variation in the motors such that any two motors will not produce the same voltage when turned at the same speed. Add to that the resistance of the power leads and their length, temperature, connector resistance, etc. and you will see that precise speed control and distance is a going to be inaccurate. It may be possible for a theoretical controller to "learn" the circuit charachteristics, but at varying speeds and the short distances traveled I think there is still a lot of room for error. I would need a little more convincing before I would jump in on this.
