It's great to have more and more of these projects, especially since frontend dev is such a huge time sink (if you're not doing it 100%).

There are also some similar projects, for example flask-meld [1] for flask (also via websockets but falls back to polling if not available) and django-unicorn [2] (afaik only polling).
