Maybe we could convince openstreetmap.org to support kml. http://www.openstreetmap.org/index.html
Yeah, or create a more detailed basemap for the WikiMiniAtlas... ...which incidentely I'm working on!
May I suggest again that you guys hold your horses on this list.
It is fairly discouraging for someone who spent _months_ of work to develop an add-on to Wikipedia/Commons to see people on some mailing list who have just spent a few minutes with the material make suggestions to toss all the work out the window.
Please please try to inform yourself about the current status of the Geocoding projects _before_ you start a parallel discussion about how to make everything "way" better. This is very unproductive. Especially as some conclusions from the list have been reached months ago on the project page already, making this thread seem like - sorry - a show off for whippersnappers.
