There were several discussions about the road import already, you can search for "osm roads" to get some of them.
In short, OpenStreetMaps come with a usable vector database; once there's an importer it will be possible to import and enable the OSM road network (and possibly more, like the fields/pastures and other data).
A tracker for stuff being worked on .. probably wouldn't work. Too many open things, some classified, often times the tasks change dynamically (like for twentieth time I had to interrupt working on the biomes because other things are more important for the first commercial use of the engine). Not the least - we aren't disciplined enough to update such a tracker regularly
