maybe this could be done with the new plugins structure.. but

calling a modeling app from inside Poser. not having it built in no, but being able to pass a figure out to a modeler, work on it, then bring it plus any added on models (such as clothes) back into the workspace near seamlessly... instead of mucking around with importing and hoping it works.. very much I suppose like the link to zbrush, but expanded for modelers like Wings, Blender, etc.
