We demoed Nefsis today. I really liked the format and the multiple views for participants. It was easier to use than Live Classroom, but I need to know more about pricing and LMS integration. It allowed annotations and on-the-fly loading of materials, which is good. Cost could make it prohibitive. JUST LEARNED THAT NEFSIS IS NOT MAC COMPATIBLE.
Also, heard about Agora which can be installed in Sakai our LMS. This is extremely important for student/faculty member seamless access. I need to learn more and confirm if our IT will integrate it in our Sakai at some point.
