I remember reading something about this being incorporated into some brands of TVs as well preventing you from changing the channel during a commercial, or some other nonsense. Of course, simple laws of supply & demand will prevent this from going out there (unless a bunch of people buy those). Still a load of crap, and I'd rather not watch a show than be forced to sit through commercials and not be able to do anything about it.
Of course, yet another benefit to building your own computers: I won't implement the blocking of the fast-forward button
