  Interestingly, the control system world has had the need you speak of
for some time.  They use "historians" which accept and catalog large
volumes of data in literal real-time, calculate derived data and store
them, and provide access in real-time for control algorithms.  The
market-leading example is Pi from OSISoft <http://www.osisoft.com/>.
They have some installations with millions of points (data sources) that
update on about a 3 second interval.  I'm not sure how that compares
with SQL based products, but they claim their product is faster.
