You're not familiar with Facebook? Google Docs? I mean it does tell us something they have logins: it's expensive to build complex single page applications There's no incentive to do that for free and in the open. I started my comment by explaining why you're not going to find the golden case you're digging for: even when provided you'll haughtily share how jQuery could do everything shown, and as I explained you don't see most of what is being done. Everything is easy until it's not. Maybe you should share examples of things you worked on with a larger team and show us that we're overestimating the limitations of manual state updates.
