Don't know, whether I understand this correctly, but isn't this a huge
security/privacy problem?
Let's say, user A starts his frontend, stands up, walks to the scanner
and puts some confidential or at least private document on the scanner.

would it be possible, to add an option called button-state to saneopts.h ?
button-state is an option of SANE_TYPE_INT with SANE_UNIT_NONE and

option).
If a frontend detects such an option, it can use a timer to
