Ummm.  I forgot where I was going... Got stuck in the exit lane and
am now suffering from vapor lock, stuck here in the traffic...

What I was thinking about was implementing it like one of those computed 
attribute thingies in Tabula <!--#var latest_bobobase_modification_time-->
which I could do in an external method, as I discussed before...

How would that fit in with your suggestion? (sitting here, playing with
the clutch and flipping the turn signal switch)
