Hi Craig,
I recently started a project decentralizing a Moodle master server to gain consistent accessibility at remote nodes, aiming at an improvement of course quality at Open University of Tanzania. This thread pops up at first when I google around and I think we do share some goals and needs. Since this thread is a bit old, I'm wondering how this project turned out to be and whether you have some documents or experience that you could share?
Thanks in advance!
