In Can OSS Integration Server Software Enable EAI/BPM, Dennis Byron discusses whether open source software can compete in the integration server market.

Research has shown that often when cost is such an inhibitor, open source software (OSS) can help…On the other hand, everyone agrees that BPM/EAI/integration software is among the most complex software developed and offered in the market. Therefore—conventional wisdom says—it is no place for the OSS culture and development model…Conventional wisdom is wrong again.

createTank’s elemenope SOA framework is mentioned as one of the few FOSS competitors in the market area.

The elemenope framework is a classic integration server based on both OSS terms and conditions and OSS culture. It has been in development since 1999, almost since the start of the integration server era, and it has also enabled a service-oriented architecture (SOA) since before that term became popular.
