 Rex, I actually think Michael's answer was bang on target. You only have to look at the archives of the W3C Web Services Architecture Working Group to see the difficulties involved when trying to gain consensus on the definition for basic terms like "Service". > since it is almost guaranteed that the future of computing will be > dominated by the paradigms being developed in this field. How far into the future are we talking, here? The whole of computing, guaranteed, really? Web services do have some significant vendor backing, but still have some real political and technical issues and so much to prove. The potential to reach the 'Web' vision for services remains, but is likely to be somewhat different to the tower of Babel currently being battled for. As someone wise said recently (i wish i could remember who): the future is often out there in the long grass, where no-one is watching.
