Ok, i will do it.

For GnomeScan, i wrote a Glib-GObject wrap to SANE. It allows to use
GValue to hold option value. You may have to write a dbus wrapper around

The problem is that SANE backends are even slightly different from each
other which can make a frontend dev crazy. So you should really write a
tiny dbus wrapper around SANE types.

Keep up the good work. I intend to build GnomeScan on top of imcad for
this summer (SoC).
