Would there be interest in/nned for a "map:" namespace which returns a map image of given coordinates?
For a country, city, region, river, lake, mountain etc. one would type, say, "[[map:1.2.3:4.5.6]]" to get a rectangular map. That would be generated by some free map service (there are some, though I don't remember any URL). That would avoid the copy'n'paste action of current maps on wikipedia, and save disk space ;-)
I thought I'd better ask before I try implementing...
