Common Lisp bindings now part of ZeroMQ 2.0

Today Vitaly Mayatskikh announced the inclusion of his Common Lisp ZeroMQ bindings into the ZeroMQ 2.0 source tree. ZeroMQ 2.0 is a high-performance messaging system, which is great news if you are trying to build distributed systems in Common Lisp.

Previously, available Free Software alternatives for Common Lisp messaging included CL-XMPP (XMPP client only) and CL-RABBIT (Lispworks only).

Note that ZeroMQ 2.0, unlike version 1, no longer implements AMQP, due to performance reasons.

Do you happen to know more about the trade-offs between XMPP and ZeroMQ?

ZeroMQ: serverless messaging, multicast, no persistent queues out of the box

XMPP: needs a server, but can work behind NAT firewalls using HTTP, no persistent queues out of the box

XMPP has horrible overhead, especially for binary blobs (needs base64 because it's based on XML).
