Seems you're in a similar position to me. What do you think you'll do
about the duplex thing? The suggestion to buffer one full page might
be viable... although it's a shame, the Windows software that came
with the scanner supported duplex out-of-the-box.

I'd love to. But how do we handle things like different allowable
resolutions, different maximum page sizes, and so on. It wouldn't be a
problem to produce one source code file that, using "#ifdef"s, can
produce three or four different drivers, but what options would we
have if we were to try producing one single driver. An extra
parameter, "--model", maybe - but how would we communicate to the SANE
front-ends that certain settings e.g. of the "resolution" parameter
are only available if the "model" parameter has been set to something
specific? I doubt the current mechanism supports that.

I won't bother since it's all a "draft" anyway. The main work will be
figuring out *how* it works, and once I've got that, I'll be willing
and able to build m3091 support into any clean, combined driver. I
