I did not do it, I examined the hardware to see if it could be done.
It can, but you are going to have to write all new code for the
embedded controller in the Ipod Camera Adapter.
My transfer figures are for transferring images from a camera to the
Ipod.
The built in software at this time only copies from the camera
to the IPOD not the other way.
You would have to write all that code yourself and with the limitations
to the hardware speeds, in my opinion it is not worth the effort.
