I actually don't think that the government will have to do this, because as consumers we do it already for them:

Have a notebook in your house? Nice, your camera may already be watching you and the mic listening to you.

Have a mobile phone? Nice, you are now under surveillance 24 hours a day. The 2 cameras can see, the mic (and now apparently even the speaker) can listen, your location is 100% tracked, the gyro can let hackers know via your current vibration profile if you're in a bus, train or car, etc.

All this could be partially prevented by hardware switches for each sensor. Are we consumers out on the street fighting against this and/or voting with our $$$ to prevent the loss of privacy?
