Depending on context, it also turns every object into a potential bug / movement sensor. I think this field is pretty interesting, especially for buildings where fault finding and maintenance can be very expensive. Things like wireless strain guages in reinforced concrete, embedded temperature and humidity sensors in walls, the future does seem likely to have cheap sensors absolutely everywhere.
