It's re-assuring that others also believe that Grid and Management are application domains and are not infrastructure, and that ironically using a pure SOA rather objects with angle-brackets would confer significant benefits. Side note: There is a good discussion going on over at the WS-GAF mailing list on stateful Web Services - the gist is that all useful services are stateful, but if you want to make them scalable, robust, and loosely coupled then you should go SOA not resource/object-oriented.
