I'm not saying that you can do this today, but...
Couldn't this be implemented as an ADF-like feature of a backend?
A backend for a scanner with a handy button could have a "multiple pages
via the button" mode. In that mode, upon receiving sane_start() it waits
for the user to press the button before starting the scan. Trivial!
Only problem is that I don't think there is any way in SANE1 for the backend
to specify that it has an ADF (real or virtual). So this scheme would only
work for the scanadf frontend, which just assumes that an ADF is available.
(But, that's still extremely handy for scanning a lot of pages.)
