WordPress Plugin: Show coComments
A new plugin is out and has even been recently updated after finding a problem or two. It is called Show coComments.
Show coComments creates and unordered list of one of your configured boxes on coComment. Which one it uses is configurable in the options page. Most of the configration is done by coComment with thier comment box creator, however there are a few options you can change such as showing the actual comment text and displaying a link to the coComment page for each post(not comment).
