You can use comments and store individual ratings using add_comment_meta().
You would also probably want to store the rating average using add_post_meta(), since it’s rather expensive to calculate it on the fly. Each time a rating is added or removed, you will have to update this average.
I don’t know if there are any plugins that do this already; haven’t searched.
