[GRASS-user] IDW (or similar) and cost surface

I have implemented a while ago a cost-based kriging that I used exactly 
in that way.
You can see the paper and sample code here:

There is a GRASS script that helps to compute the cost-based distances, 
and then there is an adapted geoR library that performs the cost-based 
kriging computations.

Let me know if you need help in applying it to your case.
