Sorry, it's on my other computer - I didn't keep the file on this one since it's too simplistic for a real product. :D 

But certainly there is no copying of geometry whatsoever.  The cylinder/boxes do not have the same poly count or vert arrangement as V4 (in fact, causing them to HAVE the same count/arrangement would be nearly impossible, especially by this method).  You can choose to have the shrinkwrap shrink to the nearest vertex, but that produces screwy results - the above was made using a snap to "nearest surface point" so many verts will be in the middle of V4's faces instead of lying vert-to-vert.  This effect is greatly magnified after scaling, smoothing and subdivision have been applied.  

In other words, there is no conceivable way ANY DAZ geometry could be extracted from any product made using this method, so I can't imagine why it would be a problem (though again, I will comply with their EULA once I've reviewed it).
