I was able to get the functionality I need by using the split-ncv2.patch 
Charles Goyard sent to the list on 3/29.07.  Thanks Charles!

I must admit that I was/am a little concerned about using it because the 
patch hasn't been merged into Hobbit, but I really needed its 
capabilities and decided to give it a chance.  I'm not a C programmer, 
but from what I can tell the patch adds the functionality I need w/o 
impacting the default NCV module and that was reassuring to me.

The only outstanding issue I have with the patch is that I cannot I find 
a way to limit the # number of lines/graph, so on one of my load 
balancers I have 12 lines on the same graph.  Using "variablename::5" in 
  GRAPHS in hobbitserver.cfg doesn't do the trick, but that isn't enough 
of a drawback to stop using the patch.
