I really like Omri's excellent video on the Microsoft Web services vision. However I did feel discomfort in the notion that only a dozen people in the world will need to really understand all these specs because code will hide all the complexity. That's a massive underestimate if this stuff really is successful. I also felt uncomfortable at the REST straw man argument.
Rather strangely about half way through I was reminded of the Goodness Gracious Me character "everything comes from India": "WS-Policy - Indigo!, WS-Transfer - Indigo!" .. stupid i know, but there you go ..
