What's the Best Way to Build a Linux CD-Rom JukeBox

An Anonymous Coward asks: "Picture this: a mega SCSI based server box with a bunch of cd-rom drives. What's the best way to build this beast so that it can serve iso-9660 and hfs CDs to smb/cifs, nfs and appletalk clients? Is there any particular way to deal with SCSI IDs and LUNs? Is there an easy way to improve request performance by caching on disk or RAM?" Hey...sounds like an interesting topic!
