A Possible Design Idea...

In my Java version of the databus, the way I have done this sort of thing is
have a listener-filter that listens to the high-frequency/low-level events
on a slot, performs some sort of analysis (normally using a state-machine),
and then posts some appropriate low-frequency/higher-level events to a
different slot. Listeners on this alternate slot then perform the
appropriate actions when they are notified.
