Pinpointing voters on a map

Wired News are carrying an article about the use of Geographic Information Systems (GIS) in elections.

I spent most of the last election campaign wishing I had some way of linking my database of voters to street maps. This stuff is not rocket science, but the biggest impediment seems to be the limited availability of the geographic data itself, i.e. maps. In Ireland there seem to be two main suppliers of map data: the Ordnance Survey and a company called Mapflow. Both charge rates which would put this outside the budget of most campaigning organisations.
