Ok, what about the following approach:
-By default, no values are saved to disk.
-If the user creates a directory $HOME/.tevion9693usb, then the files
 are saved there. For saned, this means that the values are used by all users
 that are allowed to scan over the network, if someone with permission to do  
 so created /home/saned/.tevion9693usb.
-The backend supplies two options:
 "Save calibration values to disk (if possible)"
 "Calibrate before next scan"

Are there any problems with this approach ? I don't want to be the one who 
introduces a new security problem :-)

Thanks,
