Too Less Power to play around.... (Score 2, Interesting)

Idea is great ! But doesnot seems to be practical with Computer having moitor,dvd drive,cd drive....etc. Even If we use USB device which is drawing power from the PC and ultimately from the network which can only supply a limited power. So no of USB devices connecting to the computer will also be very limited. Theoretically if a computer consumes Microwatts it can get power over wireless LAN...So no more Cables!
