If I'm reading it right, the directory service today is a single host. That was very misleading after these statements (which suggested something closer to netflix eureka):
"Zookeeper provides a strongly consistent model; the directory service focuses on availability."
"Baker Street doesn't use Zookeeper or the other popular service discovery frameworks because we wanted a simple, highly available service, not a strongly consistent one."
Edit: Which is not to say that the project isn't interesting, just that some of the copy felt like a bait and switch. :)
