zmqpy - alternate (cffi) zeromq python bindings

zmqpy is already compatible with zeromq 2.2.x and 3.2.1.

The goal of this project is to provide a CPython/PyPy compatible ZeroMQ bindings for the Python language.

It uses cffi (http://cffi.readthedocs.org) as integration mechanism with the original libzmq code.

API Example

It looks like Pyzmq.

import zmqpy

context = zmqpy.Context()

socket = context.socket(zmqpy.PUSH)
socket.bind('tcp://127.0.0.1:5555')

socket.send('message', zmqpy.NOBLOCK)

socket.close()
context.term()

Benchmarks

This (naive) benchmark compares PyPy + zmqpy Vs Cpython + PyZMQ

It sends 10000000 10 bytes message == "aaaaaaaaaa".
