> Apple could release some gems from the Shake code base into the Blender compositor

You're assuming they still have a copy of the source code :(

I'd love to see some of the Shake feature set make it into Blender:

    - node-to-code  + code-to-node
    - 2.5D motion blur for transforms
    - general concatenation of image transforms for single pass resampling.
    - general C-style code expressions available in any text field of the UI and being able to reference any other variable in the entire UI
    - ability to call any function from libc / external DSO's directly from any text field in the UI.

etc ...
