The answer on both counts is no. Firefly uses the Reyes renderer subpixel polygon subdivision method which has a lot of advantages over mesh subdivision techniques (such as detail) but doesn't (and isn't intended to) work in raytracing. There was a long investigation thread in the now defunct beta forum last year. Prior to SR3 Poser attempted to emulate displacement by moving mesh vertices, but often gave wildly unpredictable results and CL replaced it with bump mapped reflections in that SR. It would be possible to use volumentric calculations to give displacement in raytracing, but the raytracer would need to treat every polygon in the scene as a volume and that would have a major impact on the render times of Poser scenes.
