Hi Micha,
I have soil samples from boreholes where i have data points at every
meter interval and where soil type changes. i would like to create a
weighted average of soil property for lets say the first 1 m below the
DEM, so that i can evaluate potential for infiltration across a watershed.
You can use v.what.rast to read the DEM value into the attribute table
of your points. Then you can do whatever calculations you need based on
that.

Or, if you mean zones of equal height, you can transform them to vector
polygons and use v.vect.stats on these polygons and the points.
