out of topic, but I really wonder why you'd really need to put such
data into RRD. If that's for graphing only, you could utilize Gnuplot,
or probably hack RTG (http://rtg.sourceforge.net), since it uses SQL
storage as backend.
RRDtool is excellent in processing periodically updated data series,
but IMHO for single 10-minute shots it seems to be the wrong tool.
