I didn't know if you are aware of this...
The DEAL lab and CIT on East Campus have a Content Management System for web pages that they implemented at the beginning of 2006. I believe that it uses Lenya, but I only use the system, I don't have anything to do with the technical end of it.
The folks at CIT that I've been working with are Gary Zhu and Lana Johnson.
So far, 3 departments and a number of smaller projects on East Campus are using this system.
Hope this helps,
