I was going to ask this question here, but then I found the answer, and
thought I'd post it, perhaps someone out there wondered the same thing.
Q: I've downloaded the ISO images for _____ (fill in your favorite
distribution) but I want to do network installs without keeping a second
copy in my "regular" filesystem. How?
A: see
http://www.neci.nec.com/~sven/linux/iso9660.html
Also try 'man lndir' -- lndir is a really cool command I hadn't seen
before.

p.s., Anyone collecting these bits for the web page?
