This issue has been raised a few times in the past (with no actual responses)

I think it should not be so difficult to include a section called "neighbors" 
in the msh file that includes a list of elements that are adjacent in a 
certain format. For example:

$Neighbors$
nelement nneighbors element1 element2 ... elementn
$EndNeighbors$

A refinement would include which are the nodes that define the faces that 
share both neighbors. This optional information would allow gmsh to be used 
with the finite volumes method.

Any comments from the gmsh developers?
