I was actually thinking more along the lines of plugins so that multiple
types of routers could be added.

On the Navigation settings page (or maybe a new page) the router you wish
to use can be selected from those you have installed.

I was looking at using gosmore initially as it gives most of what is
needed already and it uses the osm data although preprocessed.  I think it
can be setup quickly to give a reasonable solution to routing without
being online.

Currently I only update the osm data for gpsdrive on a monthly basis
(Australia only) and it would only be a matter of incorporating the
preprocessing into that update.
