Very nice they are getting some really good looking results there! Thanks a lot for that link I hadn't seen that one before.
Although I have seen similar research and methods from a while back in similar implementations.
As you say this is a pipeline and one which is designed around getting a high quality visual result, doing quite a few passes on the data to get the final result.
While this is super cool too, I am interested in something that is focused on low latency / speed for more realtime skype like applications.
I imagine that this will be a huge field in a few years as VR/AR glasses get more common. It would be great with an opensource alternative to what Google, Facebook and MS are going to produce. But maybe it is just too early for that right now?
