Hi, Michael, This sounds like an interesting new aggregation function. My time is fully committed for the next few months, so I might not be able to implement this feature. If you can code up something, we'd be happy to put it in FastBit..
By the way, this aggregation similar to median would not be able to be processed by parts. Therefore this would be an expensive operator.
