I was thinking exactly the same thing. NSA's TAO has been modding routers since forever, and that's in a country with actual rights and stuff. Would not be surprised if every single one of these is going to have some undocumented functionality on an obscure encrypted band, like "kill nearest American soldier".

EDIT or, worse, ping your location every X seconds on this band, and let us look at the audio/video when Y command is received.
