I don't see why not (and you gave some good free examples). At its most basic
level it is a matter of requests going to a spatial server and the spatial
server sending vector or raster data to the client (using vector data requies
JavaScript while using raster data only requires a web browser; but vector is
more bandwidth-friendly).
Lat/long could be fed to such a spatial server along with some default values
for extent and projection to obtain a basic map. There are a *great* many
similar websites that do this on the Internet. If you have used MapQuest, then
you have used such a system.
The real issue are data; Only the U.S. has very comprehensive public domin
spatial data. A separate WikiGIS/WikiMaps project (we own the .com and .org for
both names) would probably be needed to improve those data and create data for
the rest of the world (also serve the result to all Wikimedia projects as a
part of Wikimedia Commons). *That* would be fairly unique and difficult to do,
since I'm not aware of any such similar project based on the Internet.

PS - the whole idea of copyrights on spatial data seem to be absurd to me; how
could anybody claim to *own* any exact digital reproduction of the street
network for Paris or the exact location and shape of the Zaire River? And yet
this type of thing is *very* common in the GIS world (but I also think it is
absurd for people to copyright *natural* DNA sequences and patent their
*natural* products ; I guess I'm weird that way). Argh!
