ClearBoard
If ClearBoard works as advertised, it’s easily worth the $100 price of admission. Try it, then (please!) let me know what you think.

“With the help of ClearBoard, every whiteboard, blackboard, or flipchart can be used as a digital-board (electronic whiteboard), in the sense that this software produces the same, or even better, digital images as a digital board can do.”
