BTW, some users missing push-mode scan, totally missed from SANE. But it 
requires the whole image logistics to be rethought: user presses some 
buttons at scanner, scanner connects the computer, some daemon accepts 
this connection, then somehow GUI popup should occur with a question, 
how to handle received image.

It doesn't fit well the UNIX multiuser model. At what desktop this popup
