When you say that.. standard PS2 or USB mouse could be used for that! You can connect as many as you like and changing mouse functionality to a jogwheel or a trackball is very simple. The optical sensor has well-defined DPI with +-1.5% tolerance, for jogwheel that should be enough and putting it near the wheel to sense the movements too. Just you need to make a filter for random rapid movement of the mouse. I can recommend laser-lighted mouse in that case too.
