Tangled Web Services actually gives a relatively coherent account of what is the oldest game in the technology platform part of town:
“So the question still remains—what is the programming model for Web services? With their answers, vendors have an opportunity to change their relative competitive position.

And this is where users will have to worry about getting stuck.”
