Personal Service-Oriented Architecture

Also John Udell discusses SOA (Service-Oriented Architecture). The word SOA seems to have originated at InfoWorld. I am not sure I understand what they say. They talk about events (result of?) written in XML and of flows, which can be inspected and act upon. Below that is a messaging infrastructure of XML-messages (as envisioned in Longhorn). The quotes that Marc Canter added to this gives me a very deja vue feeling: see objects as services, in fact web services.

It is an extremely good idea, but what is new here? That is has been adopted by Microsoft (at last)? These models have been around for many years. The first time I really used it was within NeXT with their distributed objects model. They also moved this idea to their desktop with the Services-menu. But think also of the pipes in the Unix-world. What do I miss here? I miss the deployment. This is where Microsoft certainly can help.
