A data point:
The Canon MF4880dw -- a multifunction device with network and USB
interfaces -- has two buttons, labelled Scan->PC1 and Scan->PC2,
which seem as if they could be of interest to sane. When I attempt
to configure one of those buttons using the front panel, selecting

I've seen it. And I
There is this old project of mine called "scanbd", the "scanner button
daemon". There wasn't low / no activity in the last year(s), but it is
still functional because it is strictly POSIX conform.
If anyone is interested in taking care of that, I would be very happy.

level, polling isn't going to tie it up and saned can always return a
"We're busy scanning" signal.
