One of the main aims of TEAMMATES (the project) is to train students in contributing to non-trivial OSS productions system. TEAMMATES has received contributions of 300+ student developers and have done more than 200 releases over a six year period.
Because TEAMMATES (the product) is a software for students by students, students can relate to the problem domain better. The scale of the system is big enough (~125 KLoC) without being overwhelmingly big.
