Indeed : they are used to get their files in PSD (or Illustrator) with
the right colorspace set :)

For now, we (Mandriva) have been able to avoid this issue.

Moreover, we have to provide backgrounds and screensaver which looks decent on
random joe monitor, which is almost never calibrated. Of course, they
won't look the same if
we were trying to compare each of the monitor, but that is not our goal.

Ok, that is what I was wondering.. I guess I'll need to do more tests
on both monitor settings
and dispcal.

Thanks for your time.
