What about new rating plugin?

Are you by any chance planning to create a rating/review plugin? It would be great to have a plugin to collect reviews and ratings of a site using a form and collect that info in order to show certain bits on different places on your website.

For instance the average rating on the main page, the user rating on a review page, etc. And of course to have a multisite option, so each subsite can have its own rating. Perhaps have a public overview page to create credibility.
