        First of all, thanks for the pointer!  It's exactly what I've
        been looking for, and I hope that BitTorrent, Freenet, GNUnet,
        and the other P2P suites and protocols will migrate to this new
        URI scheme for content-derived hashes as soon as this schema
        will finally become a standard.

        However, there's no need to refer to the future for an example
        of such an URI scheme, for there's one in the past.  Namely,
        urn:ietf:rfc:5538 finally codified the well-established practice
        of using //authority/ with the news: URI scheme (as per the
        prior specification, //authority/ was to be used with nntp:
        URL's, while news: was reserved for authority-less URN's.)

        For instance, the message I'm replying to could be referred to
        with any of the following URI's:

news:[email protected]
news://news.gmane.org/[email protected]
news://news.gmane.org/gmane.network.peer-to-peer.p2p-hackers/3597

        Namely?

        What I'm interested in right now is where this I-D is being
        discussed, as I feel that the empty-authority (ni:///) form is
        unwarranted there just as well, and a no-authority URI (ni:)
        should be used instead.  (Just like the news: examples above,
        but contrary to the file: URI scheme.)
