Hi Rory, I guess it depends on the precise requirements. Are you asking whether sections of geodata can be rendered into 'picture files' for view later? Of course this is basically what is happening all the time. If you want a 'slippy map' displayed in a local webbrowser this can also be achieved by having a local webserver or tile cache on the same machine that the web browser is on. Richard wrote up how to build/run a tileserver on Ubuntu: http://weait.com/content/build-your-own-openstreetmap-server > > If not, it should be easy enough to generate and create a CD, which > leads me to my next question.

So one machine has priority covering a specific area, and when that area is left another machine takes over?
