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)
