I am planning to have a look at it in due time, but it would be helpful if someone else wanted to take a look at this. Or do the LinuxCNC port. I, too, have been thinking about some kind of LinuxCNC jail where only the most trusted prisoners would be allowed access to the Machinekit-HAL. However, I didn't spend any significant time on this. I think Zultron or ArcEye did something, so maybe have a peek in theirs repositories.
