The only thing I don't like about the Extremis-powers-the-rings theory is that the concept of the Ten Rings obviously predates Extremis. We know from the comics that Killian is the one who develops Extremis; and I firmly believe that Mandarin has secret ties to Killian's company (which I also firmly believe is Advanced Idea Mechanics, which we've seen in set pics). Maybe Killian made prototype Extremis nano-weapons for Mandarin's rings?
