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 ?
