Multidimensional Scaling (MDS) is certainly an option to be considered.
Its suitability depends, of course, on the specific application.
In my case, which is conceptually similar to Martin's, that option was
discarded.
And I think I can explain why whith this single image:

Ooops, you're right, sorry.
This shows that nobody tried to use it before, haha :)

Hi, Martin
Two years ago there was a similar discussion on the list:
Hi Facu,
great, this is just what I have been looking for. You say that your
modifications to geoR are open source. On your website I found the geoR.dll
file, but no source code. The .dll is of little use platforms other than
windows. Is there any way I could get the source?
Thank you for the
Hi Martin.
I have succeeded in doing something like that.
Please see http://dx.doi.org/10.1016/j.mcm.2009.05.021.
I used GRASS for the computation of the non-euclidean distances and
modified the geoR library in order to be able to estimate de variograms
and perform kriging prediction with thos

Hi All,
I want to kirg fish and seabird densities within an estuary which has several
arms. Since neither organisms cross land, the appropriate distances would not
be euclidian but over-water (as fish swim). There are several papers,
describing this problem and how to deal with it (see below),
