This looks like a great project, and nice to see them supporting OSM. Google gets (rightfully) lauded for offering quite good maps[1] of much of the developing world, but I recently checked out the OSM map[2] of the city I live in (Dakar, Senegal) and it's just as good, if not better. Bing Maps[3], by comparison, thinks there are 2 roads in the entire city.
