If you tell me where your Attached-KML geoJSON-files are on Toolserver you can get ours and we will also transform it also for you in WGS84.
Ha, the KML data is fetched directly from wikipedia using an XMLHTTPRequest, and transformed into a GeoJSON-like datastructure. No need to store anything on the toolserver. Thanks for the offer to supply WGS84, I'll try conversion in Javascript first (modern JS engines are so ridiculously fast it'll probably be unnoticable). But I'll get back to you if it doesn't work!
