The network protocol is pretty well specified in the SANE spec
<https://sane-project.gitlab.io/standard/1.01/net.html>, there are many
frontends that implement sane-net clients:
http://www.sane-project.org/sane-frontends.html. I wrote the jfreesane
frontend, and I've also written a wireshark dissector for the sane net
protocol, all using the spec. I don't think the spec addresses automatic
discovery.
