Another option which you could look to is:

- use Cirela-OSM (http://forum.world.st/ANN-NetGen-OSM-Roassal-Demo-tp4791158.html), which will give you the OpenStreetMap background for any place / any zoom level

- and a combination of FreeBase, GeoJSON in a Roassal view

(See the geometry properties of freebase at: http://www.freebase.com/location/location/geometry?schema=)

In Cirela-OSM, you will find examples of queries to FreeBase to retrieve country / cities Lat/Lon coordinates and use them in Roassal. You also have an example of querying raw OpenStreetMap data as well.

Good luck for your workshop.
