Portability here is a tricky concept. Python is portable in the sense that it rnus jsut about everywhere. However, there is another sense in which it is much like interoperability. Python has a complete C backend, so in theory you can easily interface with C code. However, Python objects do not play well with C++ objects (which has given us a lot of grief in the PyLith project). If everyone agrees that all OO is done by Python, and any interface to C/C++ must go through the Python C bindings for objects, than this might work. We should have done this in PyLith.
