Here's one for David [SiT] Carter-Tod: SourceForge: Project Info - The BOSS Online Submission System

The BOSS Online Submission System is a course management tool, developed by the Department of Computer Science at the University of Warwick. BOSS allows students to submit assignments online securely, and contains a selection of tools to allow staff to mark assignments online and to manage their modules efficiently. BOSS also contains automatic testing facilities suitable for computer programming assignments.

Looks interesting.
