Your observation is correct, but I'm pushing for the SHA-1 string because it could be efficiently parsed, stored, and used; it's essentially an optimization (or a preparation for an optimization). If that's not a good way to approach it, then I'd be satisifed with just a straight (name,email) pair or any other reasonably unique string. On a more general note, the idea of a uuid is to distribute the process of canonicalizing identities.
