Nice. I'm a big fan of little to no backend as well. I've done a similar simple web server in Node.js which does nothing but check to see if a static file exists to serve the request. If so it serves that static file. If not then it serves the index.html page. The index.html page then has Backbone logic to parse the URL and serve a proper view based on what the URL is. It matches up nicely with the REST style URL's and you still don't need a heavy backend to do routing that way.
