Any interest in getting these custom mods into Orca?  Send them to  
the list and we can get them checked in (after a review, of course).

About the peak and average, we could bump the RRD file format.  This  
would be a rather significant change, as doing so would cause Orca to  
reprocess all the raw data files and I don't know.

With both the AVG and the MAX RRA's, does the RRD module plot both on  
the same plot?  Do you have some plots you can share, either via a  
link or attachment?
