Re: DNS based URI without any set access semantics?

How about the "tag" URI?  draft-kindberg-tag-uri-02.txt

   This document describes the "tag" Uniform Resource Identifier (URI)
   scheme and the "tag" Uniform Resource Name (URN) namespace, for
   identifiers that are unique across space and time. Tag URIs (also
   known as "tags") are distinct from most other URIs in that they are
   intended for uses that are independent of any particular method for
   resource location or name resolution. A tag URI may be used purely as
   an entity identifier.
