Great news. I've been meaning to calibrate a few monitors but I didn't want to shell out for a proprietary colorimeter with its restrictive driver software. Reading the description of the device it's simpler than I had expected. I suppose the secret is to make sure you have exactly the right shade of red, blue and green in the colour filters and that you know exactly what proportion of incoming light they let through.
Hopefully, too, there can be a database of colour profiles for common monitors which can be included with Linux distributions. Yes, every individual monitor is different and should ideally be calibrated individually; but still a general profile for all monitors of a certain type is better than no profile at all.
Perhaps the LiveCD software could ask if you want to submit your profile to a central database.
