  Hi Nick,

  so you say that:
  - frontend/sane-net crash
  - system shutdown of frontend machine

  is handled by the tcp stack for unix, win32, os/2?

  Then I would suggest we set the time to e.g. 24 hours
  (this makes sure that saned does exit if an unexpected error occurs)
  and add a function in sane-net (may be supported by saned)
  that makes it possible to find out if saned has exit.
  Then we can add an error code SANE_STATUS_NETWORK_CONNECTION_LOST
  or something like that and the frontend will be able to inform
  the user about it.

  Bye
  Oliver
