PyZMQ - Python bindings for ZeroMQ

Python bindings for ZeroMQ. ZeroMQ is a small, fast, and free software library that gives you message-passing concurrency for applications in most common languages.
The ZeroMQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.
