I finally installed the metroguide software last night (under VirtualPC). It does have an option to export routes to a CSV format that would be trivial to convert to the format gpsapp is using if anybody is getting sick of MapsOnUs. Of course that still doesn't help with in car routing.

You know what would be really neat? The software has the ability to export a chunk of actual map data to a gps using the garmin protocol for routing when you aren't at the PC. I wonder how hard it would be to parse that exported data. I would be pretty cool to get gpsapp to emulate a garmin gps and just export map data straight to it.
