In GRASS we are working at directed graph library (dglib). It is at a early 
development status, some functions are already implemented (shortest path on 
digraphs, depth-spanning, minimum-spanning). There are modules from Radim 
Blazek for steiner-tree and salesman-problem that will be integrated into 
dglib. The API is still unstable but I'm hardly working on design it.
Poor documentation... A lot of work to do...
Maybe we could share some info...
