From the front page of the sourceforge site:

Most of the map files used by RoadMap are generated from the TIGER files provided by the US Census Bureau, and from the RNF files provided by Statistics Canada, and thus cover northern North America only. There has been recent work on deriving RoadMap data from other sources, including postgis and other shapefile-based formats, but this work is either not on the main development branch, or very experimental.
I live in the UK, no interest in/availability of tiger maps. I do note that there's been some recent work to be able to use OSM data, but afaik RoadMap doesn't support routing, so I'd prefer to do dev work on something like Navit which uses OSM data for mapping and routing. Perhaps if a version which supports OSM were released there'd be more interest.
