As the main developer behind the Mitsuba exporter I like your proposal.
It would greatly improve the current workflow.

But I would also like to make another proposal.

- Add to Blender a bpy.props.NodeTree(type=NodeTreeType) that can be attached to ID. This way there is no need to fill the bpy.data.node_groups.

- Add a function to NodeTreeType that can be called from blender or python and returns a list of accepted data sources by that NodeTreeType. That way the node editor can show the appropriate options to the user to select the correct data source.

What do you think? Possible?
