not yet, but it could be done quite easily I guess, given the
proper motivation and skill. All you need todo is to write an
alternate rrd_fetch function which fetches data from the database
instead of the RRD and does the necessary data resampling while
doing so ... could be expensive though ... rrdtool is very fast ...
