Comment 2 for bug 640722

Okay, I've posted my request to exiv2 developers at http://dev.exiv2.org/issues/726

This exact feature request is now made pretty clear.

Also I thought you can support custom file masks via video (not photo) copying framework.

Plugins and help in development: I am ready to help. I do some bash & python scripting, so I can make some Nautilus-style (or your custom style aswell) scripts if I have some free time and ideas. More about nautilus scripts: http://www.brighthub.com/hubfolio/matthew-casperson/articles/83630.aspx . I can send you .dng conversion script for example when it's ready. My email is public if you wish to discuss about it.
