As far as easy_install is concerned, it is only looking at the web
page and scraping links with the rel="download" attribute. It doesn't
care whether that is in the "Download URL" spot of the official PyPI
metadata or not.

The download_url metadata of distutils can only accept one URL,
though. One option is to have the Homepage have links to the release
tarballs and the Download URL point to the SVN repository, and also
upload release tarballs to PyPI where possible.

Here is one example of a project that has an SVN repo as its Download URL:
