Sorry, I should have made clear, for this project we're quite happy to run
a seperate mapnik/openlayers server showing the data. Although I would be
quite interested in building that up into a more general historical map
server (ideally kept in sync with "current" OSM but historical information
as well), but that's just a personal project (with lots of problems!) and
not what's needed at the moment.
