For such an infrastructure (which apparently intends to mirror the files as well), I insist that a propagation of download counters is made mandatory. The only mirrors that can be excused from that are private ones.
This may not apply to pypi as the sites you get to mirror you may be different but Linux distributions have found that it is easier to get mirrors if the mirror admins can run as little custom stuff as possible. ie: If they can retrieve content from the master mirror via a simple rsync cron job that they write they are happiest. We have found other ways to generate statistics regarding download in these cases (for instance, based upon how many calls to retrieve the mirrorlist or how many calls for specific packages via the mirror redirector).
As I say, whether this is a problem for you will depend on the willingness of the sites that are mirroring you to run your scripts with code that you've written rather than themselves.
