Initial Comment:
Hello, 

beside v.random or r.random to set points for latter analysis into an area other options would be very handy:

- sampling every 10th point of raster
- linear sampling: small areas have less points than larger areas

other sampling strategies could be implemented see Dylans page: http://casoilresource.lawr.ucdavis.edu/drupal/node/320

this ought to be either done per raster or per raster but separated by classes in raster. 

Martin
