What code is the review feature of directory listings using?

Hi,

I was just wondering what code for reviews is the directly listing plugin using?

The reason I ask, is that it should be pulled out and applied to all custom post types, buddypress profiles and multisite blogs. Then the community could rate all these items.

If the rating code could be applied to all items in Post Indexer you would have the most killer rating plugin for Wordpress!

Any chance I could get this as a feature request?

Any +1's ?

Cheers,

Johnny
