I can see one thing that would need to be considered - is if you make templates that have various settings but contain no 3D data would the author's details still be embedded into the documents?

What if, and I have done this before but not in MoI, you use geometry as a reference and you build a housing around another 3D model. Then when you are done with your model or housing you then delete the original model leaving the geometry that you made, thus only your creation exists. However, according to the file the model belongs to someone else.

I see more headaches than anything else.

Just my two coppers.
