Hi Mark and others,
I don't think this is currently possible in QGIS. But I think that there
is definitely a need for such a functionality. Directionality is
important in GIS and QGIS should some day provide a way to display arrow
heads and other markers at vertices, similar to the concept SVG supports
markers.
Also, in conjunction with GRASS, such a functionality is quite important.
