The really basic stuff is the same for everyone since it's
dictated by the way Python works on computers :-)

So you want the indirection to happen even before fetching
the download package ?

That's a good idea - and also a lot better than the web page
link scanning that setuptools is doing.

It goes a bit in the direction of what we had in mind with writing
for our clients: a tool that looks at the Python installation and
automatically finds/downloads/installs the right package from
our website. Only that we wanted to put up a single index file
for that tool to use, not one per package.
