I'm not quite sure why you are getting the 'permission denied', but what you 
currently have won't work anyway.  You need to have the 'nohide' option in 
your exports file, or you will not be able to see the CD-Rom anyway.  See man 

Try instead:
/mnt/cdrom    host_cdrw(ro,nohide)

And then
# mount -t nfs host_cd:/mnt/cdrom /mnt/cdrom suggests that 
updating to the latest nfs packages might be in order to fix the 'permission 
denied' error.
