I also needed general comments on my adp pages. I didn't want to have to put all my adp pages in a separate package just to get an object_id,
so I ended up doing the following:
1. Added adp as a file extension in the param AllowedExtensions in the static-pages package
2. Went to /static-pages/admin and clicked "scan the file system for static pages". This gives all my adp pages under www a page_id.
3. I then used Joel's method of adding a comment to notes (see above) and applied it using the page_id of my adp pages.
