Hey Fletcher,

It seems you have some very interesting ideas!

It seems such an endeavor would involve quite a bit of inferential (as 
opposed to descriptive) statistics.  As I see you have a stanford.edu 
email address, I gather you're on top of such things. :-)  How would you 
propose such multi-variate time series data could be best correlated and 
statistically analyzed, across many user-friendly rrdtool deployments?

Very interesting -- I'd like to hear more about your ideas!
