Comment (by neteler):

 Replying to [comment:17 mlennert]:
 > One remark on v.surf.idw: IIUC, the current distance calculations only
 work in projected locations. It might be worth introducing geodesic
 distances...

 FWIW, in v.distance the function Vect_line_geodesic_distance() and related
 are used for that.
