Pretty much all of the DVCS web frontends allow users to get tarballs
of any revision they like. For example, the "bz2", "zip" and "gz"
links at the top of my Mercurial repo for line_profiler:

http://www.enthought.com/~rkern/cgi-bin/hgwebdir.cgi/line_profiler/

Click the "files" link for any of the previous revisions to go back in
the history, and click on the "bz2", etc., links to get past
revisions.
