I'd definitely be interested in this concept. It would be great if it could somehow access POTH, so that it could be used alongside my current software setup. I always liked the ExploreStars motion controls, with the variable speed and ramping up/down when starting and stopping movements, but I don't really use ExploreStars anymore. POTH motion control is tiny on the screen just clunks on/off at whatever speed you select. If you were able to emulate smooth scope control from a physical device like the 3D mouse, that would be fantastic!
As an aside, I may be trying to set up my rig for visual use by using SGP to run plate-solving on my guidescope, and slew and center on targets, just like I was imaging but using my diagonal/eyepieces on the main scope. All my imaging targets are already loaded in SGP, so it would be nice to tour them visually sometimes. So having a 3D mouse control would give me a physical hand controller-like experience if I wanted to move the scope around while viewing. Anyway, sounds like a great idea to me.
