Article says "using radio equipment already built into may drones...." Doesn't say which ones and I would be willing to bet that the only transmitter in my phantoms is the lightbridge. Since it is linked and coded to the RC, not likely that it could be modified to broadcast ID and location info. Even if, it would require some serious FW and software modifications. Oh, and by the way, the FAA would still have to deal with the congressional mandate prohibiting any new regulations on hobby RC aircraft including quads.
