As I see it the [WS-*] is so large and complex, and the participants so tightly coupled, that scaling to even enterprise levels is out of the question.... you will not be able to use this technology to build a fully distributed enterprise architecture. I am shocked. I mean there is so much evidence to the contrary. Er, isn't there?
You can bet that lots and lots of enterprisey types will go with WS* though, because of the soothing balm of WS-fuscation coming from all of the analysts they listen to (along with the herd behavior they cling to) - better to be wrong as a group than to be right as an individual. When your highest desire is to sit in "low information density" meetings so that you can get other work done, it's easy to fall for this kind of crap.
