I'll be the first to admit that I'm a bit of a luddite when it
comes to feature creep.  To my way of thinking the primary value
to RRD is the data file format itself.  The graphing features are
nice but not strictly necessary.  IMHO the stack language used
by rrdtool graph seems much more cumbersome than doing similar
things using gnuplot, one of the perl or python graphing modules
or even excel.

I don't want to discourage anyone from implementing this functionality
and more.  But if it were my choice I'd be asking for better featrues
to describe what goes into the data file and getting those descriptions
back out again.
