The question is what the final purpose is. For smaller scale
graph stuff i am using postgis with the osmosis schema. I am grabbing
all ways and then splitting ways at junctions etc so in the end you
get a graph (which i am solving as a steiner tree). Takes some seconds.

This works pretty well but most likely not on a per country size.
