Hmmm ...In what sense is something like Amazon.com or eBay.com "late bound" if you look beyond the human interaction part of it (e.g., the human scrolling through a list of query results and looking for something to buy or bid on)? And in what sense are the HTML forms and POSTS on the client side and the CGI/JSP/ASP stuff on the client side *conceptually* different than Web services? As a thought experiment, consider if one of these sites used client side code (maybe employing XForms) to generate a SOAP message from the user input rather than simply POSTing name-value pairs, and the server side extracted the information it needed out of the XML body rather than out of the HTTP parameters. What is REALLY different between "Web services" and the successful systems on the Internet that invoke significant server-side processing rather than simply moving representations around? Unless you tightly couple the client-side code to the actual objects and methods that are ultimately invoked on the server side (something that virtually everyone I know of agrees is foolish!) then the SOAP/XML approach seems architecturally more or less the same as the HTML/CGI approach. What is different is simply that more of the nuts and bolts are standardized using XML, as I see it anyway.
