Well, it seems like DAZ are pretty eager to catch up with Poser's feature set. So I wouldn't be terribly surprised if they added support for more interesting shaders fairly soon. Don't they use 3Delight as their render engine? That's a Renderman compatible renderer, so I suppose it should be able to outdo Firefly easily if they really used all its abilities.
