So we've all calibrated our screens and our printers.  There seems to
be plenty of software out there to calibrate our scanners too.  There
does not however seem to be much out there for calibrating our cameras.

This is tricky though.  The image captured is somewhat subjective. 
Normaly I shoot with a colorchecker chart just as a reference.  I did
however run across the ACR Calibrator script which is supposed to help
calibrate Adobe Camera Raw when importing images.  After some
experimentation it has turned out that under controlled lighting
conditions even the lens used has a subtle effect on the colors
captured by my camera.  Unfortunately after measuring my chart with
PFP I noticed that the colors published don't (cough) exactly match
... which isnt unusual with large batch production methods.

How careful are the rest of you with color when capturing images? 
Would it be accurate to say that, like printing, having the colors
captured being pleasing is not nearly as important as being deadly
accurate?
