If the speaker could output frequencies above ~22kHz, and the
microphone sampling rate could be tweaked high enough.. you may be
able to build a primative close-range comm protocol with that?

Actually, even in the human audible spectrum, it'd be a neat way for
two Neo1973s to handshake. 10 bonus points if it sounds like R2D2.
