Supplemental:
The creation tools just directly make an ISO file, they don't have to
loop mount anything. You only need to horse around with loop mounting
if *you* want to see the finished ISO file as if it were a disc that
you'd put into a drive. There are various software players that will
just play the ISO file directly as if you'd loaded a disc, too.
What tools would they be? That sounds interesting.
