I'm presuming that Kai's link is showing only current data. So what's needed is
1. A pre-redaction planet snapshot, loaded into a DB. 2. An installation of the OSRM that uses 1 for its calculations 3. Changes to Kai's work to look at both source, compute the deltas and color the results appropriately 4. Stuff I missed... Can we install these components on the OSM US server(s), or does anyone know if they're already available elsewhere ?
