I'm in the car with Jarrod on the bay bridge. We were just discussing
this issue a bit. I tend to agree with you that it belongs outside of
SciPy, perhaps as a Scikit. Several tests have been failing for quite
some time, which is problematic when we're trying to push towards a
more regular release cycle. It seems very unlike the rest of SciPy as
it deals with inline compilation of C code rather than generic
scientific code. The licensing issues are also a bit onerous.

My two cents,
