I'm thinking about doing a binding for libgphoto2, the library behind
gphoto2 (www.gphoto.org).

First, is there already a project like this? I've searched RAA and
RubyForge and found nothing. If you know of such a project, please let me
know.

Second, is this something that would be useful? The gphoto2 application is
already a good CLI to libgphoto2, and gtkam is a GTK2 GUI for the library,
so the two most obvious uses are already satisfied.
