network-transport-zeromq-0.2.1.1: ZeroMQ backend for network-transport

Implementation of the <http://hackage.haskell.org/package/network-transport network-transport> API over ZeroMQ. This provides access to the wealth of transports implemented in ZeroMQ, such as in-process, inter-process, TCP, TPIC and multicast. Furthermore, this makes it possible to encrypt and authenticate clients using ZeroMQ's security mechanisms, and increase throughput using ZeroMQ's intelligent message batching.
