Footprint finding for blog search tool

I recently published a lil search tool to easily find a list of blogs that use the Disqus blog commenting plugin. It worked out really great and I have a pretty decent framework that I could now expand to make full use of other blog commenting softwares.

I am interested in footprints for plugins such as sezWho and any other that people may know of, anyone that helps will be looked upon generously when it comes to releasing my tools, as well as gaining much love and karma

Any help is much appreciated guys.
