I think cffi is well worth considering as a possible inclusion for Python 3.4. (In particular, I'm a fan of the fact it just uses C syntax to declare what you're trying to talk to) I'm cautiously +0.5 because I'd really like to see a strong comparison case being made vs. ctypes. I've used ctypes many times and it was easy and effortless (well, except the segfaults when wrong argument types are declared :-). I'll be really interesting in seeing concrete examples that demonstrate how CFFI is superior.

My main issue with ctypes, other than confusing API, which is up to taste, is that you just cannot wrap some libraries, like OpenSSL because of API vs ABI. OpenSSL uses macros extensively. Another point is that even C POSIX stdlib gives you incomplete structs and you have to guess where to put what fields.
