Might be unneeded complexity. Recently we have needed Django's features (or at least its made life a lot easier), but definitely can do without them for this.
And personally, I'd like to be writing Go code here, not Python/Django.
Keeping it Go + JS (Angular + Socket.io) sounds really awesome to me, and is all that is needed.
This would bypass Django altogether. See http://godoc.org/code.google.com/p/go.net/websocket and maybe http://www.gorillatoolkit.org/pkg/websocket
I say that if we force SBHX people to use Chrome, Firefox, or just about anything pretty new in order to use this app, that's fine.
