This seems like a really interesting step toward HTML/CSS 'libraries' where you have reusable styles on reusable small chunks of DOM. The to-do list example they use is a good one. You'll occasionally see jQuery used like this, to instantiate blobs of page in known configurations. I don't know enough about, say, SproutCore or JS GUI libraries like it to know if any of them use this approach, but it seems like an obvious thing for them to do. Or I may be overrating the approach. Still, sounds useful.
