Hi folks...I'm still unable to get cdaudio working over nbd.
I can export the device fine, nbd-client connects fine, an audio cd is
in the drive and can be played locally. I tried various players, XMMS,
kscd, beep, even the venerable workbone commandline player, none
recognize /dev/nbd0 as a cdrom, or the player reports no Table Of
Contents readable from nbd0. In all instances possible, I have the
player set to use digital extraction, not analog.
ll /dev/nbd0
brw-rw-rw- 1 root disk 43, 0 2007-09-30 14:01 /dev/nbd0
I straced workbone to see what, if any, issues may exist. Below is the
complete output of strace log:

I can export data partitions from hard disks just fine, and read them
via nbd-client, so I know that much works, but I'm at a total loss as
to why I cannot get cdaudio to work.
Any other avenues of troubleshooting I can look at?
