This is the perfect story to read on halloween. I'm really curious about that high frequency speaker data transfer theory. That sounds fun to play with. Anyone seen anything about this? All I found (via very, very casual googling) was this Chirp thingy a year ago.

Here's a Javascript library that provides ultrasonic audio networking in the browser. It's more hobbyist or proof of concept at the moment. Ultrasonic communications has already made its way into kids' toys ( Furby for example ) Those two are unidirectional but show it's possible. It is a leap from the possibility to using it as a command and control system, but not much of a leap.
