At long, long last:
CNS: AirBears Guest Account Service: Guest accounts allow visitors short term access to the UC Berkeley AirBears wireless network where available on campus. Accounts may be created by Faculty and Staff and are valid for a period of up to a week. AirBears guest accounts only allow access to the wireless network; they do not provide access to wired network services such as LIPS, campus email or other services. Longer term visitors who require such services must apply for an affiliate CalNet ID in order to be eligible.... Faculty and Staff may create, view and modify guest accounts via the guest account management system.
