If anyone is interested I've done some tweaks to Gareth recently (though it still hasn't got the review functionality).

Firstly, I updated the README, requirements, settings setup, etc... so that it's relatively easier for someone to jump in and try out. (Well, long as you don't run into gevent installation issues).

I also started adding STOMP, WebSocket, etc... handling. So fetches are being done in a separate process (long as you're running the taskrunner) once you request it. And progress alert live updates are only a matter of finishing the STOMP -> (Web)Socket connection and the theme code to update the dom.
