You don't need a complex stack to build a Python web app with a UI that updates in real time (using websockets).
This is the presentation I gave at the PyWaw 2015 conference at the end of May. I'm not sure if they recorded it, or when the video is coming out if they did, so I've made my own. The slides are here.
The architecture presented here is also what I'm targeting in the new Spa web framework. If you're interested in building on this, let me know!
