I'm thinking that I would only want to import the Poser scene if I bring in the entire animation so that I can incorporate it into the VUE scene with lights, shadows, etc.  Otherwise in most situations I could composite the Poser figure into a VUE scene depending on where they'll go....I understand there is considerable overhead if when brining Poser into VUE although this is very handy.
