The Canon PowerShot camera series comes to mind. I have an S5IS, and play 
around a little with it, but haven't done any development work. With the 
CHDK (Canon Hacker's Development Kit) you can do all sorts of things 
inside the camera, such as run a script to detect motion, set 
speed/aperture outside the manufacturer's default ranges, and convert the 
USB input into a remote camera trigger.

I can conceive (although I haven't into it) that you might be able to 
insert a script that would accept GPS position data through the camera USB 
port, and write it in the EXIF data on each photo as it is taken.

It might be worth a look to anyone interested in this with the time to 
investigate. Check http://chdk.wikia.com/wiki/CHDK for more info.
