Hi Nirav!

As you can see from Zhang's post there's a difference between making soft 
bindings using ctypes and hard bindings using the Python C API.
While ctypes is convenient to use and easy to modify since only Python code 
is involved, it lacks the ability to let the programmer to extend Python 
using the underlying C API directly. It also lacks the ability to 
intergrate easy with other Python extensions. It's also a matter of speed, 
in particular when it comes to iterations, like for collision testing and 
drawing many objects. If this can all be done in C we are better off.

My plan was to build a Python extension for 2D physics that could be 
intergrated easily with PyGame, which is also a Python extension. Since two 
people have the same plan I thought we'd join up. :)
