Basically, the problem is that Web services are well-defined right now only for very simple interactions, such as the proverbial checking of a stock price or sending an order. Most "real" interactions that people want to automate with Web services involve a number of interactions, with the exact sequence conditional on the results of previous ones. For example, scheduling a meeting with a group of people or booking travel reservations entails an understanding of the "choreography" of Web services invocations. The W3C waded into this because there are a number of partially-competing, partially-contradictory proposed specs and proprietary implementations of this kind of thing out there already. One, known as WSCI (Web Services Coordination Interface?) was published as a W3C Note in June or so; that was followed by a proposal known as BPEL4WS that was *not* submitted to the W3C, apparently because (at least one of) the authors could not live with the W3C Intellectual Property Rights policy. See the Charter of the new WS Choreography working group at http://www.w3.org/2003/01/wscwg-charter for more background on the technical problems to be solved. The gist of the article is to note the split in the Web standards world between those companies and specs which operate under the RAND license model and those which operate under the royalty-free license model for intellectual property. See the article itself and similar recent articles (such as those on the WS-Reliability spec that a number of companies preferring the royalty-free model proposed) for more on the politics and companies involved.
