gphoto2 on ARDUINO or anther AVR?

I am curious about a possibility of porting gphoto2 to an ARDUINO or another light-weight device. Does anyone have some ideas, hints or suggestions?

If you're thinking of the GNU digital camera driver software, I don't think it'll be possible. Remember that the Arduino only has 1k or 2k of RAM (depending on the chip), and photo most likely needs many megabytes. Then there's the issue of operating system and USB host interface, too.
