Ha! Putting this together with the "modem" code, I suppose that could be possible. It could be an alternative way to "network" 2 machines together wirelessly, although they would need line of sight.

The fun thing I want to do is control a Pong paddle using a laser pointer that is "seen" and tracked by QB64PE with a web cam. 

Another use case is a smart cat toy: QB64PE "watches" the floor in an empty room and tracks where the laser pointer and kitty are, and keeps moving the laser pointer away from kitty (via an Arduino or Pi connected to the PC). Don't know how hard that one is, for now tracking a laser pointer or other object on a blank background is a good simple project.
