All great info, if I'm looking for a physical location. Yeah, when I'm
looking for the address of a music, I'll search for "the intersection
in Grand Rapids, MI". GeoIP and other details take care of the rest,
and it actually comes up with the place I saw JoCo and TMBG last
weekend.

Loopbacks are easy enough. I wasn't sure that the files in question
were going to be on the filesystem, or were somewhere else in the ISO
image. I was thinking analogously to boot sectors on floppy disks and
hard disks; some data isn't directly visible on a filesystem.
