This project looks very cool, thanks for working on it and releasing it

Some people were talking about using locally stored vector data (which would mean internet connection free rendering and perhaps also routing).

One way to include this functionality in any (sweeping statement, but should be doable) of the current tile-based mapping apps would be to run a renderer in a separate app with a local webserver. This would mean that work on the renderer could be carried out independently of the various mapping apps, and the benefits enjoyed by them all.

One option for OSM rendering is libmemphis, which libchamplain is looking at using for local rendering. http://trac.openstreetmap.ch/trac/me...iki/LibMemphis, assuming there are libraries for things like Garmin data, this could also be performed in the same renderer webserver app. It would be nice to access the Maps app data, but that's probably just a pipe dream unless we do some serious reverse engineering on the Maps app

Anyway I've not tried this idea mainly due to lack of time, but it is something a few of us discussed at the first Maemo summit and it would be cool to at least give it a go.
