Seems like an interesting thing to play with, you can make your own "bait car"! If you or family member flat out lost their car key and they are far from home, I wonder if you could unlock and start it for them and would it allow them to drive away with it? (hopefully nobody you didn't want to do that)
Using cellular data connection you should be able to build on the app to track your car and do other features too I would think. Set up and send fault reports to your local dealer while you are driving maybe? Use the app to interrogate your maint history. I could see using the data service to update Nav Database, traffic, weather and other data should you not be using the satellite service.
I downloaded and played with the MyFord Touch training app that simulates the system in the car. Would be nifty to use that interface to configure your climate controls after you remotely start, then you have more options than the 72 degree default for remote starts. Other than initially being a long distance basic remote, I would hope its the beginning of options to build on.
