From the interview:
The JBI specification is a standard for what can be called a "container of containers." It describes the architecture and behavior of a framework that hosts plug-in components, and allows them to interact using a WSDL [Web Services Description Language] 2.0-based messaging system, using WSDL's services model. The goal is to allow users to obtain plug-in components that provide all the functions needed to provide an integration solution, without getting locked into a particular vendor. Components will be portable between JBI implementations.
