But, how much would I need to write to update the data in realtime as it changes in the backend?

Something like this:

    var people = dotcloud.sync.synchronize('people');
    people.observe(function(type, change) {
        // Update template here
    });

There's a live demo here: http://jsfiddle.net/q2q8b/31/
