Bantha is right. Poser users are not going to update their shaders so I consider likely that Cycles embedding will be just a 1-to-1 mapping of FireFly nodes in Cycles ones, getting out of the deal little more than a less buggy, less sucky alternative to the previous render. All discussions I am seeing in these P11 related threads are open eyes dreams since they require the use of the Elbow Grease plugin, a no-no for point-and-clickers.

If you want the real McCoy, export your scene as OBJ, bring it into Blender, redo the shaders with Cycles or OSL and render. You can do it today, for free. No time booby trapped DRM scheme involved. When in Blender, apart from Cycles yo might check also RenderMan 20 and its Blender bridge. There is a growing thread about it on BlenderArtists forum and most posters are enthusiastic.
