I have no idea if this is possible but here goes.
I was using my iphone in my bluetooth enable car and realized that while a phone call was connected I could play music/movies or whatever and it would play through the car speakers. I'm wondering if it would be possible to make an application which "simulated" a phone call to trick a bluetooth'd car for instance into thinking there was a phone call so that I can play my music via the car stereo.
