True, it is straightforward to get the tiles, and the specification is open [1]. The trouble lies with reprojecting the tiles, or informing the editor of the projection. Easiest way may be to write an extension to MapProxy/TileCache/etc so we can just use plain old TMS or WMS. Hopefully VGIN will directly offer this kind of service at some point. -Josh
