I've been watching this thread, and thanks for bit of roadmap update - I'd love to see a better plugin architecture. 

Back to updating views, along the same lines of triggering updates, is there a way to make the view updates non-blocking? I can handle scripting the updates and eventual consistency - but I can't handle the 2 - 5 minutes of blocking it takes for each view to update after a few thousand docs are added. 

- Jim
