Looking for something like Unreals node based animation tree.

I am an animator working on a project in Unity that a feel would benefit from something similar to the Kismet animation tree setup in the Unreal developers kit.

Can anyone point me towards an extension or plug in for Unity that works about the same way? I really liked the node based system and the simple way you just plugged the animations into the characters animation tree.

Any help would be appreciated.
