Where have you found free WiFi in the vicinity of the conference sessions?

• There's a table with four chairs right outside DiAnza III - also a plug there.
• There's a very strong signal in DiAnza I, but with a name like Schmi-Fi, I suspect this is a temporary rebroadcast of a signal by the current occupants. I hope I'm wrong :-)
• A little shady, but in my hotel room (Portola Plaza) I can find two unsecured wireless networks with names like "linksys". Strong signal, worked all Monday evening for me.
