This is intriguing, but unless we can decode the spreading function for a
human brain, I doubt it's possible.

Radio spread spectrum uses a pseudorandom spreading function to hop from one
frequency to another. Both the transmitter and reciever are synchronized to
this sequence. In the case of the brain, all the signals are more or less on
the same 'carrier' frequency, but are spatially separated.

A problem wiht decoding brain signals is that there is no assurance that
human brains have the same 'wiring' in anything but the grossest
comparisons. A pickup and transmitter that works for me would most likely
not work for you. If this hurdle can be passed, we should see rapid progress
