I think I found the answer, the Provider interface support StreamSource & SAXSource which should be able to give me a Stream.

With XFire, Aegis databinding provideder supported XMLStreamReader on POJOs, I thought CXF-Aegis binding would support it too.

If you want to interact directly with CXF's reader, you need to write an interceptor. You can't just write a service like that, as per Andrew's excellent disquisition.
