"Kinect 2 will be able to employ certain DRM measures depending on what it observes in the living room. If it is deemed that too many people are present, the user will be prompted to pay an additional fee to upgrade the licence."
"Theoretically, if the Kinect establishes there are more people in the room than is permitted according to the licence that users agree to when renting of purchasing content, the movie won't play."
