Matmatic does it, but that's a creature all its own...  There may be some other scripts/add-ons too.  But I use a Python utility from Poseworks: http://www.poseworks.com/serendipity/index.php?/archives/14-Rename-Node-Wacro.html

Also, I should have said above, "...the "nylon map" (Image) node, plugged into the Blending paremeter by way of several math nodes, is telling the node what is skin, and what is stocking."  You may have figured that out, though, heh.
