I'm looking for a way to track node history without actually implementing full-scale node revisioning. I'd like to be able to show my users on the node page itself a table something like what users can see in the revision history when "create new revision" is checked in the node workflow, a table like:

|------|-----------|---------------------|
| user | timestamp | comments            |
|------|-----------|---------------------|

I don't want to enable node revisioning for a number of reasons; I just want to keep a record of who updated a node, when, and any comments they want to add.

The closest module I've found is http://drupal.org/project/nodeupdates, but I am not really looking to create a feed; this is information that only needs to be visible to some users on the node page itself.
