Legal wi-fi jamming

I've heard rumors of how the 802.11 pre-n wireless networking hardware really KILLS nearby 802.11 wireless b/g networks. Today George Ou has some details. I really think this is a serious problem with the equipment coming out as it will force people to move to another wireless standard. (Somehow, this is all starting to make sense now - wait - maybe it ISN'T a problem "from a certain point of view".) Anyway - it sounds like it's really problematic to troubleshoot because it only kills the other networks when transmitting, so symptoms of the problem would be sporadic network drops. (Ouch wireless is going to be getting tricker ESPECIALLY in high density areas.)
