Thanks for that. By that I meant that a regular joe teacher is going to find it technically difficult to use. You can run an instance of open edx on your server

Thanks for that. By that I meant that a regular joe teacher is going to find it technically difficult to use. You can run an instance of open edx on your server, use xblock components and point them to a video/audio file and build a course - but that just seems like a bit too much for a teacher who just wants to assemble a bunch of content. The best solution here will win or even coexist; all the different approaches/platforms here will ultimately help the students win.
