I didn't know that: I believed the "there can be only one index" meme
which I heard during the KGS discussion.

If each a buildout can customize the index URL for each egg it installs,
then Andreas can have what he wants, which is a way to install an egg in
the same way that 'easy_install -i' does. 'find-links' is a
distraction, in this case, because it is not the same as 'easy_install
- -i' (it is equivalent to 'easy_install -f').
