I'm 90% sure it will eventually be revealed that there is some simple counter, most likely in the form of erecting some sort of barrier. Even if there isn't, it's definitely not the most powerful ability. Obviously Peter's is, as he can acquire that ability in addition to all his others. (And, in fact, already possesses it, if you think about it. If only he wasn't too dumb to know it. Recall that he also already possesses the little girl's tracking ability.)
Also that sort of ability is really only effective against people who "fight for the weak", in the words of Doctor Doom.
If I had Peter's powers and someone like Matt Parkman (or his daddy) was ****ing with me and I needed a quick solution, it would be pretty simple: locate him, teleport to him, (thermonuclear) blast everything within a 5 mile radius. Actually, I would do that regardless of whether such a person was even aware of my existence. No sense letting someone like that frollick about with that kind of potential to annoy me. How would I know to do this if I was mind controlled? I wouldn't. Thing is, I wouldn't be mind-controlled, as above, because I would have actually bothered to learn how to use the powers it would have been obvious to me I now had.
... See what I mean. You guys are too easily entertained, imo. =P I prefer shows like Dexter, Californication, and Firefly. The whole superpower thing makes me lose all respect for people who have them and aren't doing it right. It's very frustrating.
Except for Wolverine. He's a bad mother****er.
