The issue is not simply *naming* information but also *interacting* with it. In order to interact with the information, you need to bind the name to a location and simply declaring the naming schema to be location independent does not save you from this. Roy's point is (IMO) that you can use URLs (and the benefit of an existing, deployed, running system that comes with them for free) right away since you'll face the 'location problem' in the end anyhow. I think that it is far too often overlooked that you cannot abstract away the need for a system if you want to *do* something with your identifiers. In an information system, identifiers are not only names but also references (to locations) and to get to what they reference, they must be dereferenced. The need for a working dereferencing mechanism does not go away by declaring the identifiers to be location independent. You simply defer the problem.
