I use pipes. Why should I use TCP/IP. I don't want to do network stuff.
Pipes has the advantage, that I can recognize immediately if the client crashes
or exits in an unusual way. Then the server can reset the connection and is
ready.

calibration data: when the scan starts, it calibrates the color by getting the
white on the plastic. That's what always last so long befor the scanner starts
to scan. As it should normally not change, it should be enough to to it once
and save the result to a file.
nice level: unix is a timesharing system, the process with a higher nice level
gets mor cpu power. Since the scan can be time critical, it should be wise to
give the server on slower machines a higher level.
