Hi there,
I've just included support for SuperLU 3.0 in 
http://www.loria.fr/~levy/OpenNL,
it is worth it, here is the output of the included test program
(computes LSCM on a .obj file):

---> without SuperLU
Loading ...
Loaded 12917 vertices and 12812 facets
Using Jacobi pre-conditioned conjugate gradient
Solving ...
Solver time: 15.74

---> with SuperLU
Loading ...
Loaded 12917 vertices and 12812 facets
Using SuperLU, cool !
Solving ...
Solver time: 2.23
Saving ...

Note1: if you use SuperLU directly, make sure that you use
the COLAMD column permutation, there is a *dramatic*
impact on performances:
   on this example, without COLAMD -> 60 seconds
   with COLAMD -> 2.23 seconds

Note2: SuperLU 3.0 support symmetric storage, this halves
  storage requirements, I'll try to use it (since SuperLU is
  a memory-eater, this can be worth it).
