[OpenID] FW: general Digest, Vol 26, Issue 57

[Andrew Arnott]

Well, actually even with a single OpenID account and login, you can still
prevent sites from collaborating and figuring out where you've been by
comparing identifiers.  That's one of the scenarios that directed identity
in OpenID 2.0 enables.  The OP just has to issue pairwise unique
identifiers.  No OP to date does this that I know of, but it's entirely
possible and not difficult either.
