What I like is

 # dd if=/dev/scd0 of=/some/archive/file.iso bs=2048

to grab a snapshot of an ISO image, then

 # cdrecord /some/archive/file.iso

to write it out (CDR_SPEED and CDR_DEVICE set up in my environment)
and

 # mount -oro,loop /some/archive/file.iso /some/mountpoint

to mount it via the loopback device.  I think you can turn around
and export the mounted ISO image via SMB and NFS.

I don't know why you would have a problem creating a bootable
disk, if you have a bit-for-bit copy.  I've successfully used this
techinque to archive my W2K disc (full retail copy, only loaded
when I actually need to run Windows for some reason) and if they're
playing games with bootable CDs I would expect them to do it with
their own OS discs.
