Quote - Actually Kuroyume (interPoser Pro developer) has recently been working on adding support for Poser dynamic hair import, and has had some success (requires the additional Hair module, $400).  I think he has dynamic cloth import covered as Point Level Animation (PLA) but I don't see it on the feature list.  He has an example of dynamic cloth import demonstrated on this page:

Just to be official about the available support here. :D

iPP supports Poser dynamic hair (as of v1.8.1) as splines or Hair object (for best results) including dynamics simulation from the Poser Hair Room stored in the associated .dyn file in both the Pro and Ltd parts of iPP.  The support does not extend beyond basically importing the splines and animation (none of the various dynamic hair settings or materials).  With the Hair module available, you get a Hair object (linked to the polygon selection) and a spline object and all of the basic material/render setup as if you added Hair using Cinema 4D's 'Add Hair' option.  The spline object is required and linked into the Hair object to perform the PLA animation on the Hair if it had been animated in Poser and there exists a .dyn file.  From there, you are at liberty to make whatever adjustments: color gradients, kinks, curls, render settings, re-calculate dynamics (which can be done with retention of style).

Poser dynamic cloth isn't directly supported by iPP.  There are two alternative ways to go about this:

1. Import the cloth object and use Clothilde (if available).  The best option if you don't mind having Clothilde do better/faster dynamics simulation. :)
2. Export the dynamic cloth from Poser as Wavefront .obj single or multiple frames and import using the Ltd feature of Pro (or interPoser Ltd).  If there are multiple frames, the polygon object can be PLA animated.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
