In the time since you last emailed, I think we've basically determined that providing this kind of data is contrary to our goals of protecting individual editors' identity. Information from the recent_changes stream can be combined with such geolocation data to pinpoint where certain editors live. We have put that project on hold to some extent, but are actively trying to figure out how to best aggregate and sanitize this data. While nothing is going to be available in the short term, the projects to look at / collaborate with are:
* Event Logging
If you're interested in some very basic estimates, geolocating anonymous recent_changes by their IP could help you with that. I know you guys have done some work in this area already, I thought it was worth mentioning for completeness.
