Interesting thread! I've had pathpilot running on my Torus for a couple years, was wanting to dive into rigid tapping. I have added an encoder to my Lathe, and have it talking to Pathpilot and was hoping to do the same with my Torus somehow. Are you saying that your "Torus" has a servo on the spindle and it already has an encoder? My Torus (as far as I know) has a simple AC motor for its spindle.
