I think you need a PyCObject.
http://www.python.org/doc/current/api/cObjects.html

<quote from page above>
       This subtype of PyObject represents an opaque value, useful for
C extension modules who need to pass an opaque value (as a void*
pointer) through Python code to other C code.

It seems like this is meant for function pointers and the like, but it
works well for pieces of memory that need to be passed through Python
but not processed.

HTH,
