  Hi Ben, hi Nick.

  SANE defines an API between a frontend and a backend.
  The SANE network part shall be invisible for the frontends and the
  backends. This means that sane-net has to behave like a normal backend
  and saned as a normal frontend. Everything that is related to the
  network communication has to be done in sane-net and saned and has
  to be invisible for the frontend and the scanner-driver-backend.

  It is not possible to start a new network connection because
  you start a new backend that does not now about the option settings
  previously done.

  What must be implemented is a communication between saned and sane-net
  that makes sure that saned does not die as long as sane-net (and the
  frontend) is still running.

  Bye
  Oliver
