Course suggestion engines are pretty easy to start with due to limited choices and mandatory paths in programs. In fact I implemented something akin to this as part of a university assignment. The tool was actually meant to be provided for course coordinators to estimate number of students who are likely to take the course in next semester and sometimes as far as the length of a normal program. Post-release, maybe past peer history could be used for accuracy. It would not solve the volatile nature of new courses though.
