I've been thinking that the work associated with joining
administrative boundaries is similar to the coastline stuff. It
occurred to me you could make a "admin boundary checker" in the same
style as the coastline checker.

But seriously, if you want boundaries *now*, go to the CIA world
databank, download the shapefiles and be happy. They're a little out
of date but for most parts of the world the boundaries havn't changed
much. Eventually the OSM data will get to the same level of accuracy,
but we're not there yet...

Have a nice day,
