If the ID includes as one of its elements a fully qualified domain
name, and the owner/operator of that domain (as of the date and time
indicated by a timestamp that's another element of the ID) makes sure
to prevent duplicate IDs within their domain, then this would be
achieved. The domain could include an arbitrary number of levels of
subdomains or hostnames, letting each distinct machine which is
generating IDs have a unique ID namespace, reducing the problem to
making sure each ID generated by a particular machine is unique.
