That's true. Most of the files in the ISO images are already
compressed, so trying to gzip it saves only a few percent.
Also take into account that many people are downloading and
recoding the images on Windows boxes, which don't have gzip
by default.

Jordan kindly provides MD5 checksums of the ISO images, which
are much more reliable than gzip's checksums.

That would just make things more complicated, and there's no
reason for that. That's what the "reget" command is good for
-- no reason to start over at all.
