Which is to say, probably no-one has gotten around to it (unless Georg
Holzmann did and neglected to tell anyone), but I'm sure people would
be interested if you were to write and make such code available.

SWIG remains a fine way to implement Python wrappers, but I prefer
Cython myself. If you go with Cython, the Demos/callback directory in
the source tree has a good example of passing a Python function (like
a cost function) to a C library:
    http://cython.org/release/Cython-0.15/Demos/callback/
Another option for is 'ctypes' (which is included with the standard
Python distribution, and lets you avoid dealing with C compilers
entirely).
