The idea would be to send each GIOP message as one
MQSeries message, over that could be written a stream
protocol.

But the flow of control would have to be quite
different:

loop
    call sleepOnGetMessage()
    unMarshal()
    callPOA()
    marshal()
    sendReplyMessage()
endloop

So the Orb would have to run single threaded (at least
there would be only one input queue, so no need for
multithreading).

Not only, it also works over APPC
