[Routing] [OSM-talk] www.OpenRouteService.org now supports Bicycle Routing with OSM Data

Hi,

> More than 4 times in the open source community (RoadNav, NavIt, etc).

And Pyroute and Gosmore and the TIGER-based open source apps that  
were there before OSM even existed. And pgrouting, the boost graph  
library and graphserver, all of which do routing and pre-date OSM.

I don't believe this will ever work. There are tons of reasons for  
implementing an algorithm on your own:

- the programming language might not be the one you want to use
- the software might be written and commented in a (natural) language  
that you are not comfortable with
- it might be written on a different intellectual level than you  
would do it, and so it is either too primitive or too complex for  
your taste
- it might have optimizations that are unnecesasry for your case, and  
lack others that you would like to have (e.g. the memory/speed tradeoff)
- you want the satisfaction and learning curve of implementing  
something yourself
- ...

Haven't you done the very same yourself - written a routing app  
although you could have used existing libraries?

Bye
Frederik
