Comments - Allow deletion of comments on your content without Administer Comments permission? Is there a way to allow users to delete comments that are on their own content without giving access to Administer Comments?

Example:

Authenticated user makes a blog post (or some node content)
Another Authenticated user comments on it

Author does not like comment- wishes to delete.

The only option I have is edit/reply.
Should be doable with the User Comment module in Drupal 6, or the Comment Access module in Drupal 7. They both add permissions so that authors can approve, delete or administer comments on their own content.
