* Standardized paging
* Optional side-loading - GET /albums.json?include=artists,songs
* Multiple meta elements - so we'd have "albums_meta", "artists_meta" and "songs_meta" in the example above. This allows us to include 'has_n' relationship paging data.
Standardized paging seems to come up a lot, so it seems like a good thing to add once the core spec stabilizes. Optional sideloading also has come up a few times, and seems easy to add as a MAY in the spec. I need to flesh out the meta stuff in general, and the ability to have "meta anywhere" as well as top-level metas is coming.

In the light of your proposals, I'll either implement JSON API or switch back to AM:Serializers. Side-loading, paging and Ember Data compatibility are my main goals.
