Poser dynamic cloth is just a general dynamics engine, so although the results won't be the same (and settings certainly can't be exchanged) the models should be usable in any application with a similar engine - which is most of the full-service suites, at least (LW certainly has dynamics). Hair is more specialised, and so doesn't generally go from one application to another (unless you are using a plugin that exists for more than one application, and there's file compatibility. DS's clothing simulator is more specialised - it has a model of how the clothing is put together, rather than simply treating the mesh as flexible, which is why it needs special tools and why its models can't be used directly in other application s(though you can export an OBJ and use it with a generalised dynamics engines, such as Poser's cloth room).
