Not really. RFID operates the same way and has been around forever at this point. This whole thing is a gimmick, it doesn't replace switches it just makes them more complicated and moves where they're located. To switch mains current you're going to need a relay which is more expensive than a simple switch and then you're going to need to somehow tie a particular RF switch to the appropriate relay.
Sure you might be able to reduce the length of wire running through the walls a tiny bit, but that's going to be offset by a significantly more expensive and complicated control circuit somewhere. The only way this makes financial sense is if the cost of copper gets so high that running an extra 50 feet of wire is more expensive than a series of microcontrollers and relays and the unreliability of using RF for control.
