From my understanding we could not include anything that would require re-distributing any portion of the origional mesh, grouping, rigging or any other part of daz's intellectual property.  We were limited to what the script could be made to do to the end users copy of v4.  Anything else would have required redistributing v4 or a derivitive of her.

I believe there was a thread about it at RDNA and one of our members was in direct contact with daz over what could and could not be done.
