Courseware Lite?

So, I'm starting design for a web site for the OSDDDI class this fall taught by Mitch Kapor, Pam Samuelson and Steven Weber.

What I find myself wanting is a very lightweight form of courseware, preferably in php. There are zillions and zillions of examples of open source courseware and software but they all include way, way, way, way too many features.

I just want something that will allow me to enter a syllabus and other information but provide a modular list of neat features typically out of the scope of HTML. Any suggestions? I suppose I could start to write something from scratch...
