I don't think, that the distance-from-target calculation is a good solution,
because a road at the periphery of a huge city could be near to a small town in
the neighborhood than to the place with the right city tag.
Perhaps i will try the google geocoder for this task first and concentrate my
work
on the routing itself until there is a better way.

It's much more simple in many places.
The place-attribute can be used on areas as well,
not just on points.
