Sorry haven't done the things you suggested yet, as I am currently trying to test my theory. Most probably this theory is not workable.
The reason I am trying this is, we are trying to develop a system with multiple LMSes with the same layout and content, but they are actually independent of each other. I think with MNet, the super admin will have control of the client LMS, but in our case the super admin / admin of the main LMS will not have control of the other LMSes. We are thinking to sort of provide the clients with preset Moodle with all courses, settings and other plugins set up so they do not have to do them.
Is it possible?
