It would be great if v.kriging will become a native implementation once. I
still keep developing it - I have replaced kd-tree from PCL library by
R-tree implemented in GRASS GIS and now I must deal with optimization of
the final phase (interpolation itself). It takes too much time (PCL version
used to be too slow as well).

I would be grateful for any suggestions or advices.
