[sane-devel] Sharing a network scanner thru saned

I did try airscan for the Ricoh SP 377SFNwX - did not work. I can try it
with the Ricoh SP 3710 (this one has official drivers for sane/linux - the
377 does not).

Each store has ~6 machines using 1 scanner device.
The idea is to have 1 machine serving itself and another 5 machines.

I thought of this solution mainly because we use java and the only
available library (jfreesane) uses saned. Did not find any binding to

Guess each machine could serve itself, but for now I have limited options:

1) Make saned list network scanners;
2) Do a binding myself.
