This is cool. You might be interested in the synthetic sensor project - I don't think it ever got to commercial release, but the idea was to try and merge information from lots of different cheap sensors together into "virtual sensors". For example accelerometer + loudness sensor + pressure change could be combined into a "someone shut the door" sensor. Then you could make heirarchies of these virtual signals, e.g. "kettle on virtual sensor" + "morning" + "some IR signature" = "Alice is making breakfast" (rather than Bob). It's quite a neat idea, but as far as I know they never released any code for it.
