Sorry if my original post was not clear. Let me clarify the options I was
exploring:

Option 1: custom SoapHeader and modify the ws client proxy by hand to
reference the new SoapHeader..

Option 2: custom SoapExtension and modify the stream by hand via
ChainStream().

Option 3: custom Soap Extension and SoapHeader and modify the SoapMessage
via ProcessMessage().

So, it sounds like option 3 is not really an option. Option 2 means working
with a byte stream instead of a Soap API. ChainStream() is the only place we
can modify the message before serialization? I guess I'm still not quite
clear on the distinction between ChainStream() and ProcessMessage().

Given that this is all in the context of a web service request, I shouldn't
have to work at the byte level to add a soap header to a soap message. I
imagine the Stream could somehow be converted to a SoapMessage before adding
the soap header but that would be inefficient given that it will be converted
into a SoapMessage later in the call chain.

WSE is something I will explore but for the time being this is what I am
working with. I need to research Axis 1.1 support of WS-Security and compare
it to .Net.
The server side of this solution already exists and works for a different
client implementation.

Clean insertion of a custom soap header on the client side should be
relatively painless. This is how it's done in Axis (Java):

         // setup authorization header
         SOAPHeaderElement authHeader = new SOAPHeaderElement( "",
"AuthHeader" );
         MessageElement usernameElement = ( MessageElement )
authHeader.addChildElement( "UserName" );
         MessageElement passwordElement = ( MessageElement )
authHeader.addChildElement( "Password" );
         usernameElement.setObjectValue("jdoe");
         passwordElement.setObjectValue("password");
         call.addHeader( authHeader );
