[OSRM-talk] Issue #483 - Adding multiple via nodes in restrictions

[Stephen Woodbridge]

Hi Helder,

No, I updated Issue #483 with the same information. If you and other 
people have a need for this, you might want to add comment about that 
need to the ticket so we can better track who needs what.

I would be happy with just getting normalized file, prepare and routed 
to recognize it so I can load 3rd party data, but I suspect doing the 
extract is not an incrementally larger part.

I'm very impressed with OSRM as a tool and would really like to see it 
grow to a wider audience than just OSM. This is why I'm creating 
postgresql wrappers because I believe it helps bring the pgRouting and 
OSRM communities closer together giving both more critical mass.

Best,
   -Steve
