see also v.in.osm and v.in.osm2 scripts from wiki addons, and an older osm2grass.sh script there. http://grass.osgeo.org/wiki/GRASS_AddOns#v.in.osm Typically you'd use the java xapi interface to just download the region and/or map features you were interested in. Depending on what you are doing, the JOSM downloader -> Save As ... is another route. http://openstreetmap.us/uixapi/xapi.html http://wiki.openstreetmap.org/wiki/Xapi http://wiki.openstreetmap.org/wiki/Josm .osm is just an XML text file so simple to work with, gpsbabel is used as the intermediate conversion tool for v.in.osm2. Biggest trouble perhaps is that the tagging rules are by design rather informal & open-ended. Things like the number of nodes per feature are more strict as a byproduct of memory/coding limitations at the time the latest API was developed, so a reasonable GIS should have no problem with the internals of the dataset, just perhaps the expanse of it.
