AMQP and QPID - nice article by William Henry with more to come

http://ipbabble.com/2009/02/amqp-and-qpid.html is a nice introduction to AMQP, with the promise of a sample to follow - watch this space!
William points out a rather good introduction (will we ever have too many, probably) to the AMQP concepts which can be found here http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_MRG/1.1/html/Messaging_Tutorial/chap-Messaging_Tutorial-Initial_Concepts.html
