I have just done something similar but for a hasMany, I’ve put up the basics here in case it helps anyone else out: [Example of manual relationship tracking with "virtual" vars to allow for rollback of relationships in ember data · GitHub](https://gist.github.com/kevinansfield/006e403e9429cb04e608)

I’m definitely interested to see if there are better solutions out there.

@workmanw: That “BufferProxy” looks interesting, have you run into any issues with it?
