Ansible 2.0 VariableManager

Hi!

In http://www.slideshare.net/jimi-c/v2-and-beyond?related=1 and http://www.slideshare.net/jimi-c/whats-new-in-v2-ansiblefest-london-2015 a new improved Variable Management is hinted at but not much more.

Is there anything in the docs, some tutorial what the exact changes are?
And even more important: how I might be able to adapt/extend that behaviour?

I would like to write my own variable resolution against a “configuration store”
