Multisite Analytics to Include Media Downloads

I was really pleased to see the new Multisite analytics plugin - excellent piece of work, and the visualisations are really useful.

The developer asked for some suggestions for improvements and I had one major one: include tracking of media downloads.

I run a few podcasts and would love to be able to use this plugin to track downloads of my podcasts.

Currently, there's not much out there to do this - only paid external services, which require logging into a different website (such as BluBrry).

Could this internal plugin manage a redirection on each media file, as BluBrry does, and track downloads of every audio file, from every source?

I think this would be a really attractive tool to podcasters around the world. As I say, there aren't any decent standalone Wordpress plugins to do it right now.
