e.g. how about a complex event processing engine? Something like that will do a lot of the above, but the inference database stays managable since old data will fall out of the windows.

I usually dont associated CEP with this, but is makes sense. Are they meant to operate at this level (rather than at a higher level of abstraction)?

Which ones would you recommend looking at?
