Alt-Az Siderostat

With all of the advancements in Goto software, how difficult would it be to drive a flat mirror mounted on an alt-az fork mount for a siderostat? I guess pointing the mirror would be the same as pointing a telescope except that the software would have to compensate for the fact that any angular shift of the mirror is doubled by reflection. Has anybody tried this?
