Actually, no, that's not what I was thinking.
nbd currently only understands the block layer REQ_CMD (which are basic
READ/WRITE commands) if it understood REQ_BLOCK_PC it would probably be
sufficient a transport for sending the packet commands that are
necessary to drive a remote device.
The idea being that you could then do
cdrom - nbd <--\/\-->remote - ide/scsi - CD-ROM device
to drive an actual cdrom. There are some pieces missing in this vision
(like how to attach cdrom to nbd) but it should be doable in principle.
