Here you can find the lastest version of my ZeroMQ 1.x Delphi wrapper.
Some info about AMQP and ZeroMQ can be found in this post.
Please, note that this wrapper is for a very old version of ZeroMQ. The available Delphi wrappers for the current version of ZeroMQ can be found here: http://www.zeromq.org/bindings:delphi
This wrapper has been included in the official ZeroMQ distribution, you’ll find latest version there.
See this post for more info.
