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