I do not understand where you see the problem with a callback over the 
network.


frontend----sane-net=======saned----backend

backend calls callback of saned. saned sends info about callback to sane-net
and transmits the text that shall be displayed. sane-net calls callback of 
frontend. When we do not use any selections then the backend does not
need a feedback when/if the text is displayed.
