I like this idea: non-intrusive and no extra radio frequencies required, just energy-saving lights that you'd install anyway being put to good use. I wonder how many other simultaneous uses we can find for lighting other than just lighting up the room? Wireless power source, near-field communication, indoor positioning, what else?
