To be honest, it does all sound a little bit X-Files with some Clockwork Orange thrown in for good measure but do bear in mind that the Japanese are already using RFID (embedded in mobile phones) to pay for their McDonalds. How long before you have a chip that knows how far away from home you are and sets the lights/shower/heating accordingly? It is well within the realms of possibility already. The point is, it's very interesting to see the US government talk so openly about new technology. Bring on the future I say!
