I did not work on offline routing provider yet but I was experimenting
to create a routing interface for GeoClue which was used with online
routing providers (and can also be used for offline routing). I did
not publish or announce my work but if there is interest I am willing
to continue with my work. I am not yet sure if it routing via GeoClue
/ DBus even makes sense.

Simple offline geocoding could IMHO be accomplished with OSM data,
sqlite with spatialite and a custom provider, but the whole world data
might be huge - depending on what to add in the database.

For my final work at university I will make a simplified offline
routing program using OSM data which I will make using Vala and will
be in form of a library. I will announce when I will have something
working.

Besides navit and gosmore there is also monav which is also interesting.
