Maps4Mac ( http://code.google.com/p/maps4mac ) is an on demand offline
map browser for MacOS 10.6. It allows you browse and search maps, load
gpx file overlays, track your position, and generate gps logs.

It uses Mapnik as the rendering engine, and in addition to osm data
you can use it to display any Mapnik XML file.

The map data is stored in a standard database format (either PostGIS
or SpatiaLite), so you can access and manipulate the data with
standard tools in addition to rendering it.

Developing this has really made me see how limited a view of OSM data
the slippymap provides, people map a lot of useful information that
you don't see unless you download the XML. While the current Maps4Mac
rendered tag set is the same as osm2pgsql imports for the slippymap
you can still find things that don't otherwise render by searching
(e.g. the slipplymap doesn't show very many values for shop=*).
