AFAIK this is possible right now. Just use PostGis database of world, connect 
GeoServer like renderer / transformer to WMS / WFS / WSC and add WMS layer to 
JOSM. So in JOSM you could view whole world from PostGis (postgres) database.

One problem is imho sld style for rendering which I doesnt found and it 
probably have to be writen manually.

PS: searching thru WFS could be probably done by cql query. But Iam not sure 
about this.
