One of Microsoft's latest patent applications is a humdinger. It proposes to turn the Kinect camera into a snitch for movie studios, reporting back just how many friends you've got in your living room and what they're watching. Think that sounds alarmist?

It's that blatant - a system to spy on private viewing habits.
