Just a suggestion, but...
it might be a good thing if we were to first identify what needs to be
identified.
I think RFC 1992's model of an identifier (a string of some kind that
identifies an application API, and moves with the API) makes a lot of sense.
Such a thing would, for example, simplify VM motion in data centers. Taking
that model into information-centric/name-based networking, one could imagine it
being a string that an application uses to identify itself when it expresses
interest in a class of data.
If it's something along those lines, I doubt that it's in any character set,
and by the way, while it might have a current-set-of-ip-addresses, it's not an
IP address or the EID component of one. I could imagine it being almost
anything that can be built into a string, and then signed using an 802.1AR
certificate or one from another source.
I could imagine law enforcement "expressing interest" in an interesting party's
communications. Or the mafia, or the person's spouse. There might be some
interesting security angles.
But seriously, I'd suggest we start from first principles before thinking about
solutions here. What needs to be identified, and what characteristics does it
have?

For background, when I visited the ICANN meeting last summer, they were about
to launch a set of panels to advice themselves about key topics in coming
years. I promised to join one of them, on identifier technology innovation
(along with a few other IETFers). The topic for this effort is future
evolution of DNS and other identifiers, including relevant security and
management aspects. The viewpoint is primarily to look at this from ICANN’s
angle, but of course the matter is interesting to us others as well.
And perhaps we at the IETF should also understand the same things. Hence this
e-mail.
I have some ideas on what some of these trends might be. But what do the rest
of you think? Where is identifier technology going, and what new things are
on the horizon? What do we need to do with IDNs? DNSSEC? What will DANE lead
to, and how will id-locator split techniques evolve & be deployed? How will
applications or users think about identifiers in the future?
