Hi Cooper, 

I think creating a separate RRD would be a simplier way than incorporating 
a new functionality into rrdtool. 
Perhaps, this copule of my scripts (at the bottom of the page) 
would be of help to crteate your own: 

I've even created a new SourceForge project for such experiments, but 
never had a time to play with that:

If you find any of your scripts worth publishing, I can put them there too.
