This looks very interesting. I have a few questions which might get 
added to the futures if they are not already supported.

Are there any drivers yet? Which?
   * like read/write OSM data or pgRouting tables

Are there plans to support turn restrictions?
   * OSM defines edge-node-edge restrictions AND edge-edge-edge-... 
   * currently OSRM only supports edge-node-edge restrictions
   * pgRouting supports edge-edge-edge-... restrictions

There is a real need to be able to move network data between pgRouting 
and OSRM. The osm2pgrouting tool is undergoing some enhancements during 
the current GSoC. There is also a need to be able to move pgrouting 
tables to OSM pbf files so we can load them into OSRM and this seems 
like an excellent use case for this.
