We tried to address that in the section 3.4, Operational Considerations. Samita, do you think we should have some specific text there? I am always worried about forcing a trade-off between privacy and power consumption. There may be devices such as sensors in buildings for which the privacy considerations are minimum, but there are clear requirements for any "wearable" device. Ted's example of a pacemaker is an obvious one, but even something benign as "smart jewelry" would have obvious implications. -- Christian Huitema
