Those are both good questions. Currently, we're a team of two trying to maintain and evolve a production application. Believe me, we'd both love to have spent more time pushing the ball forward on Ember Data, but it just wasn't feasible. Besides, it's already on a maturation path that will resolve all of the issues before long - it just needs a little more time.

In the meantime, we're just keeping it simple and making magic with D3 and plain jQuery. We pushed all of the CRUD back to Rails, which is probably where it should have been in the first place.

Regardless, it was a great learning experience. I still highly recommend giving Ember a shot on something that's not on a tight deadline to get deployed to production.
