I'm interested in using this for home automation purposes. Accurate information about what room of the house I am in allows for the home automation interface to be greatly simplified by only showing options to control nearby items.
Wouldn't it make more sense if the nearby items themselves were broadcasting iBeacons? I think this is what Apple intends to do with the protocol.
It would certainly be useful but currently a lot of things don't have Bluetooth LE and are controlled via zigbee, z-wave, wifi, etc.. So knowing what room you are in is very useful in itself because it can help identify what target devices you may want to control.
