At the C level, there is a function for testing:
int PyObject_CheckReadBuffer(PyObject* o)
http://docs.python.org/dev/api/abs
After some digging around it appears there is not a tonne of
documentation on buffer objects, although they are clearly core and
ancient... been sifting through some hits circa 1999, long before my
python introduction.
What I can find says that buffer is deprecated (Python in a Nutshell),

I've got a case where I want to convert binary blocks of data (various
ctypes objects) to base64 strings.
The conversion calls in the base64 module expect strings as input, so
right now I'm converting the binary blocks to strings first, then
converting the resulting string to base64. This seems h
