That is pretty rad. Nice to see that support for Alembic is on the wish list. Hopefully some of the other studios will contribute back. I've been watching from the side lines hoping to see a robust framework / toolkit emerge in open source that deals with some of these lower-level issues. (Blender has pretty much nailed the high level tool kit).

If anyone is interested and didn't already know, ILM & Sony made a splash into open source last year with Alembic http://www.alembic.io/
