I wrap a PHP page around the Gosmore routing engine [1] to make it's 
routing capabilities accessible through a webbrowser. The PHP page 
behaves like an API: 
http://wiki.openstreetmap.org/wiki/YOURS#Route_calculation_API

Similar pages could be developed around other routing engines, but 
Gosmore is chosen because it is the only opensource routing engine using 
OSM data that is capable of providing routing worldwide on reasonable 
hardware.

The website http://www.yournavigation.org uses that API to show the 
routing results.
