Just found out that once you have installed and set up the "Find My Friends" app you can use Siri to tap into it.
I set it all up with my wife's iPhone and then when I was experimenting with it I asked "Where is my wife" and it came back with her location on a map saying she was nearby (next to me on the couch).
Pretty cool stuff.
Also, I don't recommend setting this up if you are a seedy character who sneaks around.
I can already imagine the first court case originating from "Siri, where is my husband?"
