Does this mean you can womble along with Claus's suggestion?  I'm
feeling a bit swamped at the moment, and not keen to undertake another
open-ended implementation exercise.  So if you can manage without, and
perhaps use the experience to refine the specification of a Really
Useful Feature, that'd be great from my point of view.
