Just a quick comment: I could view both of the individual images linked above, but the actual wiki page simply contains a blue rectangle. The SVG source displays fine, but nothing appears where the map should be :-(
The coordinates for the map view were set to someplace without map-data in the page-source. I was using the page for developing the extension and simply forgot to leave it in a presentable state... Please stay tuned for further updates soon (ESRI shape file support making a huge amount of mapdata available).
