I came across an interesting concept on Digital Lifestyles today. A london based company called En-Twyn has been able to integrate two ethernet ports into a standard power socket. It’s an interesting idea and one which I think would prove popular with many companies (offices/hotels etc).
Clearly this kind of thing could be used in different ways ie. how handy would it be if all the power sockets in your house had usb connectors integrated in this way so that you could charge your phone or mp3 player.
