So my process for getting a map while doing wifi audits is this:

1) Run kismet with GPS enabled obviously
2) Use kismel2kml to convert the xml file generated by kismet into a kml file
3) Use gpsbabel to convert the kml file into a gpx
4) Import the gpx into Maemo mapper as a POI series

I need a way to de-dupe the kismet file or the kml by eliminating multiple BSSIDs.
