Even their prototype, at $700 US is a little steep to get any signups from this list...
It would have to be productized and cost reduced more and sell at $300 to get much in sales,
and at that price it might be a little toy like fragile, or not easy to keep positional accuracy.

Enough engineering time would get it low enough, but then it might not sell enough to recover
that real value of that time spent. The above academic project is a quickie mashup
not worth copying from the sound of this excerpt:
http://2009.igem.org/Team:Washington-Software/Project "each (Lego Mindstorms) NXT brick can
only be connected to a maximum of 3 motors. We need 6 motors for this project, and use 2 NXT bricks.
We designed and implemented a Master Slave Synchronization System using blue-tooth wireless"

Sounds like something desperate to meet a class deadline.

There's a nice open hardware project called smoothie that uses some inexpensive computer chips
and can have many control outputs and has almost an OS or RTOS for programming motions.
That and a review of their code and jcline's FOSS tecan code would be more of a start.
