I could be wrong, but I would imagine that a DXF or OBJ would work, but all of the model hierarchy most likely would be gone and you would be stuck with a model that is essentially a statue.
If that happens then you would have to re-bone the model and tweak the geometry accordingly.
Poser is made to animate your model in it, for max for example there is a poser-animation import. You can open you complete poser scene(including bones ...) in Vue , and very soon, Daz will made the ver 6 of Bryce, that will open poser scenes too.
