Dunno if this is right thread to write to.
I'd like to ask you about solution for controlling cars over gprs. Here's the thing:
A person owns a 10 cars and want to unlock/lock any or all of them. And if anyone open the car door on any of a cars, it will show up on a computer. This solution should be made over GPRS, each car will have one "GPRS gate" with SIM card configured for GPRS and will communicate with a server - computer. Client then will just open a webbrowser for example. I heard about this somewhere, that someone made it (I googled it), but hell I can't find it anymore. Is anyone of you people familiar with this?
