Can you clarify your question? I'm using Cython to write extension modules that directly interface with CEF's C API. CEF is about 40k lines of C++ that programmatically controls Chromium, which itself is written in C and C++.
I interfaced CEF to Java in 2000 lines of C++
Simple, easy API. I run CEF in a separate process, and use the Window manager (Linux and Windows) to cause the Chrome windows to overlay the application windows. Standard pipes are used between the controlling process and CEF.
Email me if you are interested. As a ps -- I can use CEF from shell scripts as well. Anything with a C FFI works.

Such as by using CFFI? Cython's strength, in my opinion, is in the fact that it is its own language resembling both C and Python that compiles to down to C, rather than just an FFI.

I would say the majority of the application logic is written in plain Python, and Cython makes interfacing with it, creating higher level interfaces, and marshaling data far easier than with CFFI or using the C API directly. This is pretty subjective though.
