I'm usually not one to speak out against an innovation, but I really dont think this technology has a mass market future in the manner it's being presented. Bandwidth is not as widely available as electricity, and this technology basically uses bandwidth in lieu of electricity at the point of consumption (your house). It might be more cost effective for the consumer, provided you have no bandwidth cap, but the infrastructure is just not there.
The technology looks solid though, and I hope that a practical use for it emerges.
