That file serves as ACL for saned (server part), and you're supposed to
add clients' IP there. It does not seem to affect xsane or scanimage
(client parts) in any way.
I'm interested in knowing how to set a default device for xsane too
(which could also disable annoying broadcast-based discovery on every
xsane launch), but it looks like there's no way of doing it.
SANE_DEFAULT_DEVICE is an interesting idea, but ultimately is no
different from a shell alias.
