Hi Timothy,

One of the proposed projects for GSOC this year is all about this
exact issue.  The applications that are accepted should be posted
soon on the website:
http://socghop.appspot.com/

We'll probably have an announcement on the blender site as well, once
the offical announcement has happened.

You'll have to check and see if its accepted.
