Re: Why there aren't Internet Passports?
There was a program something like that at one time: the Thawte Web of Trust. At one level, it revolved around SSL certificates, but there was a verification mechanism that could be used by just about anybody. In essence, you were "nobody" until you had been trusted by at least one TWoT "Notary", and if enough Notaries trusted you, you could become a Notary yourself. Get blackballed, though, and you're "nobody" again -- and regaining trust isn't easy in a community where trusting the untrustworthy is grounds for losing trust yourself isn't easy. (Think of these Notaries as passport "guarantors".) It took money to run the program, though, and while it might have fit well with Mark Shuttleworth's view of the world, it doesn't quite fit Verisign's business model, so the project was closed.
