Not just now: HDDRIVER has supported packet writing for ages, so ATAPI
drives and optical SATA drives work fine. Essentially this is sending
SCSI commands via the IDE port. The physical connection is different,
the commands are the same. http://www.t10.org/drafts.htm hosts the
specifications.
Connecting old hardware like the LS-120 or new hardware like DVD/BD/DVD-RAM
drives to the Atari's IDE port is plug and play. HDDRIVER can format/partition
the respective media and then read and write data from/to them just like
with hard disk drives.

I might play around a bit with it. I had no problems so far reading data
from an emulated QEMU CD-ROM drive.
Best regards
