I do totally agree: ServiceMix 4 is not only a JBI container, and more precisely the ServiceMix Kernel which can be run standalone is a universal container (which does not include JBI by default) where you can deploy virtually any kind of artifact from web applications, to JBI applications or plain JAX-WS services.

ServiceMix Kernel is a small container based on OSGi. The latest release allows external clients to connect to it and issue commands using a simple protocol implemented on top of TCP or SSL. However, this remoting protocol has some drawbacks as the internals makes it unable to do another remote login from a remote session.
