While we are on this topic, is there a way to get a weigthed voronoi 
diagram using grass ?

The ability to rank a point to tune the area's influence would be great, 
for that purpose I've been using an arcgis'extension* but with grass it 
is not possible**. Is there a way to get a similar result ?
