Operaguy, I know what you're saying about the clothifying in Poser experiments. That could work for some types of prop hair, but again, it would be for hair that is in a ponytail or pigtails style, more than complex layered hair styles. The problem with clothifying most hair in Poser would probably be in the way the hair is modelled. Collisions would be a very big problem when dealing with transmapped hair that is layered in closely-modelled groups. Each "group" or layer would need to be sufficiently spaced to begin with so that no polygons were touching or overlapping in order for the simulation to run properly. Softbody dynamics works very similar to cloth dynamics, so I guess it's possible for someone to tweak cloth settings to react like a "flex" dynamic rather than a cloth. Again, the big problem will definitely be in the collisions, and finding the right settings. Best kind of prop hair to use for this kind of thing is going to be a style that contains minimal groups or layers. Remember, prop hair definitely won't look as realistic in it's motion as strand-based hair, especially if you needed it blowing in the wind, or wanted to show individual wisps blowing around, but it can definitely look good if used right. By the way, Carrara doesn't have it's own native cloth dynamics.
