This is my point– we can't do identity consolidation in this case.
rel-me requires that we have links going both directions.

Technorati does not require a verified email address.

I agree that this is a Good Goal (tm), but that doesn't mean that XFN
alone is the way to do it. In fact here's a better way:
1. User enters url (possible OpenId enabled) to a page that contains
their contact info and XFN data.
2. The XFN data (rel-friend, rel-colleague) is used to find the list
of people to import
3. Use rel-me hcard uid, etc to find contact information for the
people on the list.
