Except that this would cause the file to be redownloaded every time a
change happens. This will eat up far more bandwidth than using an anon
repo (anoncvs, assuming users update) or with a base tarball with diff
tarballs.

(Just a random note, both Portage (Gentoo) and BitBake (OpenEmbedded)
keep the checked out CVS tree around and simply update it for a new
build. They also keep around the source tarballs that they download,
although some people delete them for more space (although they of
course shouldn't).)
