I just put a new program: m.clump
on moon ftp site (grass/incoming)

m.clump clusters points together based on points' proximity,
point attributes, and the presence of physical constraints
(vector barriers) dividing such clusters. It first triangulates the points
using a Voronoi tesselation to determine the proximity of  points
to one another. Connections among points are maintained where adjacent
points have same attribute values;  connections are broken where adjacent
points have different values for a given attribute (field).
Connections between adjacent points will also be broken where points
fall on different sides of arcs in user-specified vector maps.
