It sounds like you are looking for a global registry of mappings from human names to various sorts of addresses. That might be something like ENUM, but with the keys being human names rather than phone numbers.
Alternately, you can see it as an LDAP directory with interactive user permissions (similar to the winfo/XCAP setup we have for presence). It would be a fairly straightforward effort to engineer a system fitting that description, but I think we'd need better defined requirements than we have so far.
For example: how does one locate the proper directory server for a given user? I doubt a unified global system to hold 2 billion to 3 billion [1] user records would be technically feasible; and, even it if is, I don't understand how it could be humanly useful. A search for "John Smith" or "Wen Zhang" in a directory containing half the world's population would turn up hundreds of thousands, and possibly millions, of records.
In fact, I don't have a particularly common name, and disambiguating *me* from the several dozen other Adam Roaches you get when you search on Google is something of a tricky task. And google gives a lot more context than any directory could ever hope to. Just looking at the top five hits on Google right now: you can probably guess that I'm not the tattoo artist or the wardrobe assistant -- but do you know enough about me to be certain I'm not the Adam Roach from Missouri listed on myspace?
In other words: I think there needs to be more scope around the problem before we start contemplating solutions; because the problem, as stated, has no workable solution. The hurdle isn't technological -- it's human.
