Sounds cool, but wouldn't such "instrumental telepathy" require rather high measure of mental discipline and concentration? To some extent these are trainable, true, but thoughts (or what passes for thoughts) are frequently scattering and wandering off.

GSlob, that's what sounds so promising to me about this. It sounds to me that this guy has trained that portion of his brain in such a manner that he doesn't really need to exert a lot of focus or concentration. As it says, he can control a TV or computer while he's doing other things. In the past, yes, you pretty much had to devote your full attention to controlling your brain waves.
