Service-learning as academic discipline?

Earlier this week, I attended a book discussion about Dan Butin's book "Service-Learning in theory and practice:  The future of community engagement in higher education." One of the main arguments Butin makes is that service-learning should have a discipline-based home in the academy.  He compares it to how feminism, which began as a social movement, became women's studies within the academy. Of course, this leads to hundreds of questions.  What would this look like?  Would the focus be on citizenship in our democracy? or community studies? or something else?  Would the experts agree on this?  I'm not sure I've formulated my thoughts about all of this just yet.  It will be something I, and many others, will continue to reflect upon.  It certainly is a fascinating idea.
