Based on experiences in SOA projects for the past few years as a Business/EAI/Data architect I am very impressed with the MEST idea. In the excellent interview with Anne Thomas Manes a few weeks ago here on InfoQ almost everything she said made a lot sense (in reference to my own experience) apart from one thing: this central notion and importance of type. Personally I think the MEST approach is a convincing answer.
Thanks very much for publishing this interview,

What you describe here resembles very much to:
1. ebXML, for the message-oriented framework with Business Messages focus
2. WSCI, as a way to describe long-running conversations
Where are the differences between what you describve here and what I pointed out?
Thanks a lot

RPC is highly coupled and often unrobust. On the other hand, message style requires a lot of work to do simple things. The design of a web system that uses a message-oriented style to query a data oriented services is not pretty.
The danger of RPC style is that we use it to integrate systems that should be decoupled. The danger of messaging style is if we use it to distribute things that really should be colocated. Fowler's first law of distributed computing will always be relevant. Let's stop using shining new tools as an excuse to ignore it.
