No luck there, he never responded.
I did run into a solution that Tweakie built, http://www.openbuilds.com/threads/software-speed-control-of-a-brushless-dc-bldc-motor-from-mach3.478/
I will probably build it, it looks pretty easy with all the work Tweakie has done to perfect it.
I think there are probably other good solutions out there, doing this with an Aurdino would be nice also, especially if you could connect it on USB and use Modbus communication to pass the parameters for the proper RC servo pulse output.
I would try if I knew anything about programming an Aurdino.
