No, I thought I remembered that a colleague once used a precompiled 
version from them... I might well be mistaken.

I've never done anything like that, but I guess you should be able to 
solve this problem using two coupled formulations in an iterative loop.

Because you then actually integrate some density on the surface region, 
and add the contribution to the equations associated with the surface 
nodes. (It's a weak, Neumann-type constraint.)

Take care,

Christophe
