I don't see a demand for non-SAX data streams. I believe that you convert
every non XML format into an SAX stream, and at the end into a binary
stream, see for example the SWF block. So I think the strength of cocoon
comes from using one language/format for comunicating between components.

If you need to hide binary code in a SAX stream, you can aways use
the base64 format.

I agree with you that the Cocoon concept can make more possible than
serving HTML page. I think that Cocoon is at the moment a bit too web
orientated, IHMO.
