This kind of thing is done (only under VMS, so far as I know) by
various vendors' packages to run optical disks. I, for one, would love
to see something similar for UNIX, but apparently standards are a huge
problem still (both in the physical disk standards and in file system
organization). 

If anyone has/is writing such an interface, let us know!!
