Fine. Just colord has to learn how to honour the calibration.

Unfortunedly paper detection is most often non automatic. Thus users need 
to select paper by hand.

PDF and CUPS have native mechanisms. Better stick to them and fix bug to 
make them possibly.

If we solve that in some standard way, this can lead to other OSes to 
follow. A colord only solution will certainly have not that effect.

weak architecture. We have cupsICCProfile for vendor profiles and 
OutputIntent as a much more robust option for user profile. (I can only 
repeat that.)
