Search for "usb wall outlet". Installing one of these will let anything that can be powered by USB use a standard cable,...

What am I missing here. I'm probably not understanding.
My search for "usb wall outlet" turns up wall outlets that "charge" USB devices.

Even if I do have wifi, isn't this concept going to require a wire running from each devise to a nearby wall plug ?
Or, is this include a way to distribute TV and network signals via the house-hold wiring, itself ?

Yes, I had heard from a cable-guy installer that satellites were too far away to give quick signal responses.
But still, that's only a minor problem and someone should be able to devise a simple work-around.
