Thanks for the head up on this. I had researched using v.out.ascii, 
d.mapgraph , awk, and finally v.in.ascii all wrapped in a BASH 
script... but it seemed a little cumbersome for the work I am doing. If 
d.bearing is has too much overlap with other modules, then I will post 
it on the GRASS Wiki for curious users. Or perhaps, some additional 
functionality or consolidation of functionality would be best.

Cheers,
