That's the question I've been asked. My wife is a doctor (she registered pain.med.pro) and I'm a lawyer (I registered internet.law.pro). I'm the Secretary of her medical corporation (she's the President), and she's the secretary of Bret.Net, Inc. (I'm the President). We used our pair of credentials inside our two corporations to register second-level .pro domains corresponding to our third-level registrations. My wife now uses pain.pro as her primary domain name, and I use internet.pro for my audio commentary and podcasts. I've been asked 'how is this different from what Encirca is doing?'

It's completely different. First, my wife and I are both credentialed professionals, with third-level registrations corresponding to our second-level registrations. Second, in our case, the users of the second-level registrations are themselves credentialed professionals; we haven't leased our credentials to someone not entitled to them. (I did give a friend an internet.pro e-mail address -- but he's a lawyer too.)

Finally, the registration agreement clearly provides that "Registered Names are restricted to persons and entities that are credentialed by appropriate entities." That doesn't only mean that the registered data in the whois has to be that of a credentialed professional, it also means that the beneficial owner of the domain name registration has to be a credentialed professional. No one can really argue that the owner of this name is Encirca (or Encirca's lawyer and accountant). The beneficial owner of the domain name is someone else (see the admin and tech contacts in the whois), and no one has verified his credentials.

If the registrar leasing programs are permitted, what happens to the concept of sponsored TLDs? Doesn't this subvert the whole notion?
