Hi Coulson,

GeoDjango is just Django. You can write an application that checks upon initialization which type of environment it's located and then you can set the DATABASES property on settings.py.

Using the technique I've told you above, you can store GIS data in two databases (for web application you can use PostgreSQL with PostGIS) and for offline use SQLite.

Natively, Django does not speaks "shapefile", so you will need to create a routine to export your data to shapefile. 

Anyways, you can always export your data to SQLite databases and use GeoDjango to render those data to OpenLayers in GeoJSON. Should work on any modern smartphone.

There is actually more than one way to do this. And without further
knowledge what you're trying to show and where it's hard to give more
details.

For example generating maps with shapefiles there is far better
solutions than GeoDjango (GeoDjango is great for querying spatially and
modifying data) like Mapnik or Mapserver on serverside. On client side
there is practically only one really working solution - Openlayers.

You don't need internet to show maps using different map servers and
browser. You can still share everything from localhost (as you do while
developing apps). It's still easiest way to do things.

I think gdal/ogr packages can create shapefiles from database if needed.
Don't know how symbology works there.
