Re: how to get "self" in callback function

You can actually mix instance methods (class methods with self pointers)
and regular methods from the stand point of C. I do all the time for the
reasons you describe. When you use the C api for python, there is a
function that calls python functions. The structure / object for those
python functions has information in it like the self pointer. It's a
different concept than a c function pointer. So to think of it another way,
when you let ctypes wrap a python function (even an instance one with a
self pointer) as a C function pointer - ctypes is really putting a shim
function in the middle. 

I don't have access to the right computers in front of me, but I'll hunt
down an example if you need one when I do.
