Actually, I don't know if he works for Daz or not.  I just met him via the Daz forums, and he seems to have some experience with this stuff.  The main issue we're facing right now is Daz Studio compatibility.  He's working on constructing a DS shader that imitates a P6 blender node, which I use quite frequently in my textures.  On the plus side, he's told me that from what he's seen, the textures are "certainly up to industry standards."
