Support for custom programmable nodes

I got in contact with ShaderForge through one of my employers. While it's a near-complete solution compared to the Unreal Material Editor, I'm missing a key-feature, which is making re-usable functions (basically splitting off 20+ nodes from my tree, eg. a Complex Fresnel calculation).

While the code-node works as a work-around, the lag of multiple outputs is annoying, as I'm currently trying to port an UDK shader which uses those.

I currently hacked in custom node support into Shader Forge, which means that at the end of "InitializeNodeTemplates" inside of SF_Editor, an event "OnNodesInitialized" is called, which I can hook into and call "AddTemplate" on my own nodes.

While this is all rather hacky, it works, even serializing/deserializing. However, it would be neat if SF would get a system for this out of the box. For example some sort of plugin-system which loads a DLL by reflection and retrieves the list of custom nodes in that DLL.
