Poser Place's V4WM uses a different rig from V4, (except for the fingers and toes, which aren't included in the distributed rigging) and yet is compatible with V4 clothing using the Outfitter utility.  It tends to be used with V4's cr2, but it doesn't have to be.  That rig is freely distrubutable.

There are plenty of remaps of various figures available, some for sale.  At most the V4 version would need to be RTEncoded against V4...
