 > Juste brainstorming here, but I could imagine that this module could be
 useful when you are using kernel-based techniques and you have to decide
 on a kernel radius. Running v.neighbors first with varying radius sizes
 allows you to get an idea of how many points you will use on average for
 determining the value of each pixel.

 > Another idea: assuming you have 360° antennas and a known reach of these
 antennas you can quickly get a gross estimate of intensity of coverage,
 e.g. for identifying (very roughly) zones with higher levels of
 electromagnetic radiation. (And yes, I know that this will be pretty much
 nonsense, unless you are in a completely flat, unbuilt area ;-) ).

 thinking of the savanna with sparsely scattered trees and animals living
 on the trees and a certain activity radius; do quick check how much
 competition between the several individuals by v.neighbourhood ...
