Nokia have software to do that with their S60 smartphones. I don't think
it has a large enough user base to be useful. (even though there are ~100
million compatible phones out there).

I think if you are going to do that, you would be better off doing it with
Bluetooth, as there are many more BT devices out there, and most people
leave BT switched on, as it does not drain the battery much.
