I think Cycles-X is the future (for Poser) and Blender is working on using Metal (on Macs).  Poser will eventually pick up all that goodness.

I'm assuming that to use Superfly (Cycles) they already have to translate the scene into a render-file to feed into Cycles.  How difficult is it to translate it into a file that can be rendered by an external Cycles renderer?  Being able to send a render directly from Poser to a Blender render node/farm would be *huge*.  Reality+Luxrender was great that way.  Non-blocking Poser while a PBR in it's own window did its thing.
