I agree about BPEL4WS, but not about WSCI.  WSCI is all about replacing
hypertext as the engine of application state.  BPEL4WS is partly about
that through its use of WSDL and assumption of specific interfaces, but
a good chunk of it is quite appropriate for use in routing, as a
complement to hypertext, not a replacement.

Hey, I coined the term RESTafarian to refer to myself! 8-)
