Hey Mike,

Heres a quick auto setup script for getting the hidden line wireframe shader created in one click. There are a few bugs at the moment to look out for but I will fix them up in time.
1. There needs to be an image plane in the scene for the shader to be created - I assume you wouldn't want to create this without already having a scene setup
2. The projection node wont auto detect what camera you want to project from so that needs to be manually selected in the imageplane_passthrough node in the hypershade
3. You still need to manually assign the shader to the objects you want to render.... 
4. It does not contain render settings as yet. I will attach that as a separate script to avoid setup conflicts
5. There can only be one imageplane in the scene.. I will fix this later on
At a base level it works with motion blur and no extra comp is needed, works straight from the box! as I said I will keep working on it as its not perfect now but it does work and no need to go to nuke for comp...
Cheers
Andrew
