I think the main point is that a URI doesn't imply "location", it is
merely an abstraction of something that has identity (I think this is
consistent with [1]). The notion of "server" is not in any way integral
to this, as I said in my previous mail [2], a server (or servers) may
show up in particular resolution mechanism but that is orthogonal to the
identifier itself. There is no dependency on client/server or otherwise.

Hope this makes sense,

Henrik
