Applications and Operating Systems as Message Pumps

I also believe that OOP will be supplanted as the dominant programming model over the next 5-10 years as the XML and Web services model takes hold. I'm already building apps where I send hand-crafted SOAP messages within the application from one piece of code to another. Remember: the OS itself works off a message pump.

I agree, but we have examples already that are far simpler than SOAP/WS-xxx. Consider the open source Erlang system. Their messaging system is multi-language through the use of erl_interface and works with pure Java using jinterface.
