Yes, the geometry would remain. In Poser, the technical side (text file hacking) enhances the abilities of the application, drastically. It allows small content creators to innovate on a level with larger competitors.

LW and Max are great. But, I think perhaps they are not exactly analogous to Poser and D|S, because of price and the lack of support from small, inexpensive, third party content providers. The content marketplace for Poser isn't unique, but it is uniquely inexpensive. I believe monopolization of the Poser content market would probably alter the paradigm and cause the majority of content presentation application users to look away from D|S. I suspect the content marketplace has been largely responsible for keeping Poser alive.

Thats not to say I believe DAZ is attempting to monopolize content creation. Its possible, but I hope they are not, for their sake and ours.
