ember-django-adapter version 1.0 is due out in January. We are finishing up core implementation and quite a few tests. Also getting documentation up to speed. Wrote an update summary here if interested: http://dustinfarris.com/2014/12/11/the-state-of-ember-django-adapter.html
At any rate, thanks to advances in Ember Data and DRF 3.0, the adapter has been dramatically simplified. It is pretty light-weight now and is very easy to get going with—just an npm install in your ember-cli project and you’re off to the races.
Server side solutions have been coming along nicely too. @g-cassie’s ember-drf project is great, and I just discovered rest_framework_ember which looks pretty solid as well (haven’t tried it though, edit: I don’t think it supports DRF 3.0). All in all, a great django/ember ecosystem is starting to solidify. Very exciting stuff.
