Right, since the scanner hardware for most devices won't actually send
a message when a button is pressed (as far as I know - someone please
correct me if I'm wrong), there's no way to do it except for having it
wake up every second or two to poll.  At least it can build a list of
the button options when the scanner's first plugged in, so it'll only
need to check as many options as there are buttons (not many on most
scanners).

That would be great. If scanner networking was that easy and more
visible with a GNOME control center applet for selecting devices to
share and managing the access controls, I'm sure more people would use
it.

Patching SANE's dll backend definitely seems like the best way to do
it - from the responses on the sane-devel list, they seem open to the
idea so far.
