It seems like yournavigation.org is still the only Routing API that is open (no API key) and has a simple, straightforward API. So it's ideal for testing and demo purposes.

It would be even simpler to use if there was no need for a proxy with !JavaScript-only clients. Adding [http://en.wikipedia.org/wiki/Cross-origin_resource_sharing CORS (Cross-origin resource sharing)] response headers to the php scripts would allow direct requests from !JavaScript (except older IEs):

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: X-Yours-client");

My use case is a demo hosted on !GitHub gh-pages: \
[http://nrenner.github.io/leaflet-routing/ direct requests] - denied by Browser \
[http://nrenner.github.io/leaflet-routing/#http://norbertrenner.de/proxycors.php?url= remote proxy (temporary test)] - requests allowed to proxy on remote host because of CORS headers
