[PLUGIN] [NETWORK] [MU] Most popular post

Hi !

I’m looking for a plugin that can genereate a list (with link) of my most popular post accros my network (subdomain) on the main site, but that shall ignore main site posts.

I’ve looked for many plugins already and one of them was almost what i was looking for : “WordPress Popular Posts”.
But, it seems that this plugin will not give me the most popular post of all my subdomain (i can have up to a hundred of subdomain). It give me back the results only for the current website.

Thank you for your help
