After playing a bit with gosmore, I noticed two things related to restrictions:
- oneway streets are hardcoded not to apply to bikes. That generates strange
  routes for divided highways. I thing that dropping the cycling speed to
  walking speed is the way to go.
- In .nl you simply can't walk or bike on motorways or trunks, but I could not
  figure out how to edit elemstyles.xml to make this happen. I have to admit
  that the trunk route maybe have to been the only connection to the
  destination. I have to experiment with that a bit more.

The svn version of gosmore.cpp I was playing with is r9774.

Feature request (I may add it myself when I have time): export computed
routes in GPX (or sometihng that can be converted to GPX).
