QPID

Rajith Attapattu presented Qpid at this month's GTALUG meeting. Qpid is an implementation of AMQP, an open data communications protocol which has among its users large financial institutions such as Goldman Sachs. These days stock trading happens at ridiculous speeds and the protocols previously used to transmit these transactions were all proprietary and extremely expensive. AMQP is free and open while retaining the same reliability. It's interesting how free can look so good when large sums of money are involved.
