So both client and server are on the same subnet and can communicate
directly with one another.

And on the client you have a net.conf that lists the server's IP
address?  You don't really need localhost on the client.

That looks fine, access should be granted to any client on the same
subnet in addition to localhost.  However, in your initial post you
mentioned that you cannot even scan through localhost even though saned
appears to be running and the saned user is in the scanner group.  Hmm.

Is saned listening, and on the right port?  Can you access saned via
telnet?  On the server, run

  sudo netstat -tunealp | egrep '(:6566|saned)'
  telnet localhost 6566

Hope this helps,
