I'm working on a project that's big into this. I extended dockspawn to support popout windows and give a breakout editor feel.
The window you popout can still communicate with its opener until you refresh or navigate away from that page. It's not ideal, but it's the best you can do without using something like signalr or sockets.io to join everything together.
