And while that is a valid concern to be noted, I don't think that it
precludes using non-URL based indicators as person identifiers.
I mean, I'm a huge proponent of OpenID and URLs for identity; at the
same time, that vision doesn't match with reality and I don't think
it's going to change immediately; therefore, XFN should not be able to
deal with the established convention even while things are (hopefully)
moving in the direction of URL-based identifiers.
In any case, consider mailing list subscriptions -- the fact that a
message is sent to the identifier (aka your email address) and you
respond by clicking a confirmation link proving that you can receive
messages sent to that email address is no different than Technorati's
clicking a link, you insert a script that Technorati expects to find
at the destination URL. The same argument can be made for IM links,
since a bot could ping you and ask you for some data that only you
would know, and if you're able to respond accurately, then you've
similarly proven "ownership" of that destination.
