+ ØMQ (ZeroMQ, 0MQ, zmq) looks like an embeddable networking
+ library but acts like a concurrency framework. It gives you
+ sockets that carry whole messages across various transports
+ like in-process, inter- process, TCP, and multicast. You can
+ connect sockets N-to-N with patterns like fanout, pub-sub,
+ task distribution, and request-reply. It's fast enough to
+ be the fabric for clustered products. Its asynchronous I/O
+ model gives you scalable multicore applications, built as
+ asynchronous message-processing tasks. It has a score of
+ language APIs and runs on most operating systems.
+
+ ØMQ is from iMatix and is LGPL open source.

+ Add support for Pragmatic General Multicast protocol (RFC 3208)
+ implemented either over raw IP packets or UDP datagrams
+ (encapsulated PGM). This requires OpenPGM library.
