Thanks for the reminder. I did this with my WA quads a few years ago. I'm living in CO now and trying to get all those quads downloaded and configured. This is the step I was missing. I might write a wiki page describing acquisition and configuration of USGS DRG quads when I'm done.

Are you suggesting adding National Map support to Xastir, similar to the online osm tiles feature? If we are lucky, maybe the tile specs are the same! I don't think the USGS wants their tiles being used with other services, but I haven't asked. Alternatively, you can get seamless USGS Topo tiles from an ESRI tile server. Looking at the license, I think it would be fully compatible with Xastir as long as we don't exceed the transaction limit. The tile format is Google/Bing--is this the same as OSM/Mapnik?

This was my goal yesterday, but I haven't got everything working yet. I still need to generate the fgd files for my USGS quad DRGs (base layer). I would like to overlay OSM street and trail data (from Cloudmade shapefiles), but Xastir wouldn't list them in the map index! After indexing new maps and restarting Xastir, all I can see is the directory. I have some older Tiger shapefiles working, so I don't understand why the Cloudmade shapefiles aren't in Xastir's map list.
