Well, my prototype rig writer & reader scripts will import some fairly complex stuff, and get things connected up correctly; It handles the standard humanoid from Rhiggit2 flawlessly, or at least good enough to work with Tischbein's weighting plug in.
I've got a whole bunch of these things I need to get refined - If I find them useful, someone else might as well...

You know, if the cmdseq("SetTag", "PART " + string); sets the part on a skelegon, it should set the part name on any polygon...
That makes something a bit easier to do in another tool... (Make hair - generates spline curves for hair guides, with the root below the scalp object, an optional point at the scalp, and the tip of the stubble. Along with either Sensei's Extend Spline, or my crude lScript version, you can pull hair guides along, and manipulate the CP's with any number of modeler tools...)
