Comments:       sane created before LGPL created.
                some of the (original) backend authors cannot 
                be contacted any longer, for various reasons, 
                not to mention each and every contributor who 
                sent in a patch. This effectively makes it 
                impossible for the SANE Project to relicense SANE

                Most can be GPL v2

Comments:       These are backends, plus a terminal command for scanning

                Avoiding damage on flatbed scanners
                Some flatbed scanners have no protection against 
                exceeding the physical scan area height. If scanner begins 
                making loud noises IMMEDIATELY turn off the scanner.

                Security problems with saned is not intended to be exposed 
                to the internet or other non-trusted networks.  Make sure 
                that access is limited by tcpwrappers and/or a firewall setup. 
                Don't depend only on saned's own authentication.  Don't run saned
                as root if it's not necessary

                Tested with usb canon, you may need avahi or net-snmp if you have non-usb?

                If error for above check
                $ scanimage -L # must show a hit SNIP means I truncated output 
                eg device `pixma:04A9180B_0581C8' is a CANON (SNIP)
                Then check configs under /usr/local/etc/sane.d/
