Has anyone considered separating the scan button > functionality from SANE so that it can e.g. launch a frontend ? Already in SANE1 it is possible that several frontends can open the same backend. (the device file shall not be kept open in the backend when sane_open is called, it only is necessary that the device file is locked when sane_start is called!). This way several frontends can be started with the same backend open and may try to look at the buttons. > > * 4.5.7 could do with some clarification, maybe even an example.
