of course there would be no market for a poser like this...  it is just a consumer market application with a "pro" stamp on it

a real pro poser would be just the core library system, the posing room, and nothing more than that, then it would need code hooks to all major modelling/rendering applications you can license. that thing would work like... lets say...like a better interposer pro (which is in all respect to the work put into it , is just a backengineered piece of buggy doo doo), just with posers native user interface ...camera controls, morph dials, and a library system on..dunno...  like floating docks similar to the gimp you can drag around the desktop ..or secondary monitor..  the material room, posing room, rendering settings would be managed by the modelling programs native modules, and the viewport would be the one from the modelling application, it would be only limited by the core applications features and performance.  a very small footprint application....or plugin... if you want to say so
i think if smith micro takes that approach the pro label would be justified, but this would also mean that youhave tocreate a unified material system, or translation so you can port those prefab settings of the products you bought to different platforms, otherwise the wholematerial thing, as flexible it would get turns into a DIY one man show, with a simple base material setting, with textures, bump maps, reflection, and trans maps which shouldnt be to hard to port to different software packages, and the rest has to be adjusted/fancyfied by yourself by adding more advanced material features this base application can handle..  a complex workflow like this would not have a place in regular poser mainstream aswell, where you can get almost everything render ready out of the box, but those products would be usable.
