Creating printer profiles with gnome-color-manager

Work on gnome-color-manager continues. Display, scanner and camera profiling seems to work very well now, but I would really like to move on to creating profiles for printers. To do this I need to buy some expensive kit, something like a ColorMunki. If anyone has one of these sitting in a draw being unloved, it would be all I need to add support to gnome-color-manager. It’s not something I can expense, as it’s not really part of the day job. Anybody?
