It's their own independant package repository also because they want
to have a "known good set
of packages" like Turbogears or Zope has.

And that's why at some point, package installers will probably need to
merge serveral indexes
that are not mirrors. This is what I've described in PEP 381

http://www.python.org/dev/peps/pep-0381

Notice that I've started this PEP right after I've set up plone.org's
PyPI system at http://plone.org/products because in my mind, every
framework should have its own package repository w.r.t the
central PyPI.
