Coming back to this: MarkusM, how difficult would it be to integrate 
that functionality directly into v.centerpoint, i.e. something like this:

v.centerpoint ... use=attr column=
and
v.centerpoint ... use=cat

which would create one centerpoint for each collection of features with 
the same value for attr or cat ?

One use case I'm confronted with right now is that I use v.cluster and 
want to find the cluster centers to then get statistics about distance 
to cluster centers within each cluster. Currently, I have to loop 
through the cluster and run v.centerpoint on each.
