edXier - The Challenges and Roadblocks?

Most problems we had was strictly related to multimedia and that we are going, exploring areas that no one touched in years or someone does. But silently in his lab and doesn't tell anyone. Yeah. Regarding edXier, I think the most challenging is the performance aspect of this. It's really not obvious, particularly because it all happens like concurrently,. So it depends sometimes on how this flow will go. And I think we will continue our work to have this automated in more and more places.
