1. User logs onto node 1, node 2 establishes a viztoauth mapping.
2. User logs onto node 3 without logging out of 1, overwriting their
session.
3. Node 2 sees "member logged onto 3" and updates the viztoauth mapping.
4. Node 2 sees "member logged off of 2" and clears the viztoauth mapping.
5. Viola, there is no active viztoauth mapping, but user is online.
Distributed programming is hard. Fortunately on Whirled we can convert any
vizname to an authname without needing a mapping, so we'll just foist that
requirement onto every user of the crowd peer services (this will break Bang).
