Idea for using a wiki with students & faculty

Sue and I were talking yesterday about components of ideas that have been floating around and how they might coalesce into one approach with a wiki.... How about partnering at the course level with a faculty member where one project/assignment the students have is to create a wiki "subject page" with annotated sources for the course as a whole or for a particular portion of the course? Perhaps then it could grow and evolve over the semesters.

It seems like an intriguing way to combine student engagement with information, information literacy, and technology. Any thoughts? Has anyone heard of other libraries doing this?
