I wonder how expensive it would be to put a GPS receiver in a cell phone and have the option to transmit the coordinates on a separate channel. There would be little difference between this and forcing cell phone companies to triangulate every call. The primary motivation for this is almost certainly "location escrow" to make it easier for the feds to track drug dealers.

Of course, one could always follow the ID4 example and triangulate cells from a single location, preferably using equipment that any small-time operator can find in his own car. -- 3bmice
