There aren't any :( but, I have to admit, it would be cool :)

I had a _brief_ look at the code in scipy/sparse/sparsetools and I see that 
you have a minimal C++ interface, which is glued together by swig, right?

I am not very familiar to the SciPy family or more precise the scipy.sparse 
module, so it would be nice with some thoughts of how deep this integration 
should be. From the top of my head:

SciPy integration in the c++ layer of DOLFIN:
As SciPy is a "pure" python library this can feel a bit (please correct me) 
unnesessary. However I see that you have some sort of c++ interface, which 
could be used. Then we need to be able to wrap it into the GenericMatrix 
class, and we also need the SciPy version of the other GenericFoo classes in 
dolfin/la. To be able to full integrate SciPy's structures in DOLFIN we 
probably need to wrap it into the DOLFIN layer. 

SciPy integration in the python layer of DOLFIN:
This should be more feasable but probably unsatisfactory, as DOLFIN and 
PyDOLIN are more or less just two sides of the same coin.

Cheers!
