Thanks for this! Any chance you'd consider writing a full blog post later down the line about your experience with this stack?
I'm working on a node/backbone/mongdb (I don't grok coffeescript) app at the moment, and any real world apps and write ups just make my day : )
By the way, GREAT app, definitely had one of those "didn't know I wanted it 'til I saw it" moments watching the video.
