This has the advantage of scaling up easily to a hardware mainframe
client, where it would surely be less expensive than a channel-
attached controller for the CD-ROM drive.

OS X, when a blank CD-R is loaded creates and mounts a hard disk
image.  When the image is dismounted, it burns the CD-R.  Exporting
the image would allow burning a CD-R fairly transparently from the
z/OS Unix.
