found this paper today (ref & ab below). I asked about the hybridity of x/c MOOCs sometime ago (Feb-2014) and got no answer...I thought it made sense at the time to think along those lines.
So it seems....it did make sense-the formula sounds like it will be (my interpretation):
edx accomodates x & c MOOCs-(cMOOCs-developed by grads) so both will run under the one roof-interesting times.Sanders et al., (2014) 'A new approach to developing interactive software modules through graduate education'

Educational technology has attained significant importance as a mechanism for supporting experiential learning of science concepts. However, the growth of this mechanism is limited by the significant time and technical expertise needed to develop such products, particularly in specialized fields of science. We sought to test whether interactive, educational, online software modules can be developed effectively by students as a curriculum component of an advanced science course. We discuss a set of 15 such modules developed by Harvard University graduate students to demonstrate various concepts related to astronomy and physics. Their successful development of these modules demonstrates that online software tools for education and outreach on specialized topics can be produced while simultaneously fulfilling project-based learning objectives. We describe a set of technologies suitable for module development and present in detail four examples of modules developed by the students. We offer recommendations for incorporating educational software development within a graduate curriculum and conclude by discussing the relevance of this novel approach to new online learning environments like edX.
