Joe is right, we are planning on doing something like that. ....once 1.5 materializes. Since much of the discussion to this point has happened offline, I've started a forum thread
dedicated to the concept over at gl Labs.
You are right that in the past it has been difficult to coordinate with all the different plugin authors. However, gl Labs
has made significant effort in trying to provide a home for plugin projects. Currently the plan is to include Joe's Caching Template Library, Forum, Media Gallery, Chameleon, CATPCHA, DokuWiki, and anything else of general value.
