Will someone please explain where this "ad-hoc is now illegal" BS is coming from?!? I went straight to the horse's mouth at www.fcc.gov, and not only is there nothing there about it being prohibited, they actually talk about it like it's just another way to do wi-fi (which it is). As a ham radio operator, I have to know about exposure guidelines as well, and there is nothing about this WRT any sort of modulation or transmission modes. As they say on Wikipedia, [citation needed].
