There are certainly many websites which do routing from OSM data, such as OpenRouteService, CloudMade Maps, and the free software Routino. However you do need a lot of disk space to store data for the whole planet, or even just one country (the Routino demo site is for Britain and Ireland only). The OSM 'planet file' data dump is currently eight gigabytes, compressed. Then you have to load it into some kind of database and index it for routing calculations. So until bandwidth and disk space improve to the point where Linux distributions can include a set of geodata as part of the default installation, perhaps routing is best done as a web service.
