Yes, we do exactly this at Tilde and it works well. This sounds like a good blog post and possibly some released code that people can use.
Because the division of labor with Ember CLI is relatively clear, I expect build tool ecosystems to build integrations with Ember CLI, that shell out to the Ember CLI tools for specific tasks as part of a larger process. We'd of course love to work with anybody trying to do this :)
Yes a blog post on that would be great! (Personally I'd love to see rails move to broccoli instead of the asset pipeline but I guess that won't be for a while if ever).
+1 I would love to see better rails integration with Ember CLI. It seems pointless to use ember-rails with the direction of ember relying on ES6 modules.
