Has anyone been able to hook up a CDR-Jukebox to a computer to do mass ripping?

It should certainly be possible. In the olden days, jukeboxes with PC interfaces used to be much more expensive than audio-only ones (£18K vs £400) but the gap seems to have narrowed: http://www.dvdjukebox.com seems to have a Firewire changer for only $1000.
