I'd bug Murray but he's packing to move to the UK to do a PhD at KMi.    (03)

Yet still down.
The code uses an interface design called PageStore and implements it with 
SimplePageStore which just stuffs things into both a java.util.Map, and 
updates a flat file.  It would be fairly trivial to implement PageStore 
with an sql database, then set that up to talk to TG.    (05)
