On another note, many universities already run and contribute to the open source Sakai LMS. It's a Java-based LMS developed and maintained by a consortium of universities. A small to mid-size university can get it running very quickly as a pilot on 1 or 2 servers using Tomcat and MySQL. It's easy to customize and it integrates seamlessly with existing university portals via CAS. Throw in a SAN for user files and it's a very powerful, scalable and low-cost LMS option that is much more usable than Bb.
