How to change font metadata (in particular, the title)?

I need a way to dynamically change the font name, and I cannot find a way to do this in .net. I'm not interested in the type of the font file, so otf, fon, ttf are open.

Things I tried:

• Using dsofile.dll / OleDocument Properties Reader. These are not the same properties that are used to access the font name.
• Name change directly in the registry.

I read that the .fon files are just hidden DLLs, ( http://www.gadgetparadise.com/901301/index.htm as one example), maybe this is the way to get to it?

Thank!
