Huh? I don't think you can export a single file via NFS (and /dev/hdc is a single
file), you'd have to export the whole /dev (not a good idea for a final solution
and you still might have some problems with permissions).
If that works, you can e.g. create a new directory like /exporteddev/ and only
create a device file for the CD (with mknod).
In addition to that you will probably have to read up on how NFS treats device
files when they are exported, you don't want it do deny access to them, you do
not want them to be exported as device files (then you'd try to access some local
drive instead of the one on the server, ls -l will show that), you'd want it it
be stupid and behave as if it didn't know that such a thing as device files exist.
