You are correct, Google isn't in Scenario 0.  Scenario 0 is simply included 
as a point of departure for explaining Scenario 1, which is a scenario in 
which the two parties are already known to each other, and thus do not need 
to discover each other.

It would be possible to add a Scenario 0b that would model the case in 
which the client uses Google to discover an appropriate Web site, but I 
didn't bother to do that, because the purpose of the document is to focus 
on Web services -- not conventional Web interactions -- and understand the 
roles that are needed under various Web services scenarios.
