Since it was asked I had ran a script to see which projects/versions that my earlier script had identified as not being hosted on PyPI to determine _where_ people are hosting these files. These statistics include dev releases.

There are 10538 total external file links that pip locates that do not exist on PyPI.

Of these here is the top 20:

    (u'downloads.tryton.org', 1201),
    (u'github.com', 811),
    (u'bitbucket.org', 428),
    (u'launchpad.net', 279),
    (u'www.doughellmann.com', 255),
    (u'walco.n--tree.net', 161),
    (u'prdownloads.sourceforge.net', 156),
    (u'infrae.com', 150),
    (u'downloads.sourceforge.net', 139),
    (u'keepnote.org', 138),
    (u'downloads.reviewboard.org', 124),
    (u'tilestache.org', 121),
    (u'mercurial.selenic.com', 120),
    (u'www.defuze.org', 85),
    (u'www.vicbioinformatics.com', 74),
    (u'downloads.review-board.org', 70),
    (u'samba.org', 70),
    (u'python-graph.googlecode.com', 67),
    (u'cyberelk.net', 65),
    (u'tuohela.net', 61),

I suspect that a lot of the github, bitbucket etc links are dev links (of which there are roughly 420 total).

Here is the complete listing: https://gist.github.com/dstufft/5137885

I ran a minor bit of heuristics to see how many were not hosted in one of the big name hosting sites,

>>> sum([x[1] for x in b if not "github.com" in x[0] and "bitbucket.org" not in x[0] and "google" not in x[0] and "sourceforge" not in x[0]])
