I doubt this would work. How could one create something that could thwart a government agency with a budget as large as it is? I'm sure they have the funding to bypass anything a private company or individual creates. The only sure way to escape the NSA would be to permanently go off the grid. You would have to live in seclusion somewhere where they couldn't track you. The best thing would be to live in a cave, and become a hunter-gatherer.
Well, don't forget that McAfee was basically making a sales pitch. If it does indeed work, we'll see how long it takes to break it. Who knows, it could be something that changes everything (unlikely). As far as the hunter gathered thing goes: looking for food is not like looking for apps for one's phone. Given the jiggliness and paleness of the majority of Americans, I doubt that it will ever come to that. Besides, that's part of the pitch: "buy my doodad that does that thing you want, conveniently!"
