From the developer:
Apache Qpid™ is a cross-platform Enterprise Messaging system which implements the Advanced Message Queuing Protocol (AMQP), providing message brokers written in C and Java, along with clients for C , Java JMS, .Net, Python, and Ruby.
Enterprise Messaging systems let programs communicate by exchanging messages, much as people communicate by exchanging email.
