I feel your pain :) This is somewhat like what I face with things like the Leap Motion or the Kinect. There are clever things you can do with them but rarely are they better than what you would do without them; truly practical use cases that justify the time and expense to implement and maintain are hard to come by. For the IoT, if you have a garage then you might want to turn on/off house lights or adjust the thermostat when a car enters or leaves. Or have a way to detect if a room has been empty for X minutes (I'm thinking sonar to tell if extra mass is in the space; Kinects are overkill) and automatically turn off lights. I'd like to be told when I'm running low on milk and eggs.
