Does the E911 work like GPS but just use signal strengh or time from various cell phone towers?
Kevin, I mis-understood your post, but now it makes sense. I thought you were talking about a camera communicating with another camera, vs communicating with GPS device (now it makes sense, that woudl be great. In fact that is similar to what the Ricoh camera does which has a GPS card. It just does not do it wirelessly.
One other feature that would be great is to record the heading as part of the track. If you have an electronic compass on the GPS receiver it can tall which way you are looking (assuming you have the reciver taped to the camera or aimed the same way). I think most of the standard track formats record location but not heading.
