Data Distribution Service (DDS) is an alternative to JMS. This spec was designed and is supported by OMG (Object Management Group). The concepts are fairly familiar to anyone who has done JMS.
RTI implements DDS in their message bus.
My feeling is that getting a large enterprise to use DDS is akin to rewiring a battleship. However, it seems like DDS has some possible performance improvements over JMS.
Anybody out there using DDS?
