Cython supports the buffer interface also in older Python versions as long as you implement your buffer methods in a .pxd file as part of the extension type declaration and cimport from that in the modules where you use it. It's a pure Cython feature though, other extensions (and Python code, obviously) won't see it. BTW, note that your question is better suited for the Cython users mailing list than the core developer mailing list.
