Lukas Tönne has received a grant from the Blender Foundation to work on the 'everything nodes' project for two months. You can read all about his plans in a summary on code.blender.org.
The work-in-progress proposal for the Blender 2.8 version plans for caching, nodes and physics is progressing steadily. If you are an experienced artists or coder or just want to have a sneak-peek, you can download a recent version from the link at the bottom.
Feedback is appreciated, especially if you have experience with pipelines and complex, multi-stage productions. The issues at hand are complex and different perspectives can often help.
