why would i want to translate materials and nodes if the reason i am going in a different render is because i want better renders.

No, you misunderstood me. The Poser nodes would be translated to the closest similar node in the target render engine. Meaning, maybe one of Poser's "fake" SSS nodes could be automatically translated to a real Mental Ray SSS node with the texture already plugged into it.

There's no way the Poser nodes themselves could be transferred, but something similar in the target app could be used.
And then you'd just tweak it as necessary to make it better.
