[Routing] Routing applications for Cyclists

[Yatzek]

Hi!

I am the third year student who is currently working on the route 
planner for cyclists. The idea is to create application which will 
calculate the route based not only on cost weighted from road types and 
distance, but also to employ SRTM elevation data and use it as the of 
the factors in calculation process.
  I am going to use OSM, and import it to Postgres with Postgis and  
PgRouting Extension. Postgis because it can describe ways in 3d and 
PgRouting because it already make a use of Postgis and contain routing 
algorithms such as A* and Shooting*.
  So, the question is: is  there any similar project ready or under 
construction? Are there any (commercial or not) applications out there 
which do routing for cyclists? The only one I know of is 
www.yournavigation.org.
I need this information for my background research and would be really 
grateful  for any help.
