WORKING SESSION SPECIFICS
Objectives	Attenuated versions of existing apis to sandboxed code. How should browsers introduce new apis into the sandbox or allow the sandbox to provide attenuated versions of existing apis to sandboxed code? For example, lets say the sandbox wants to provide an attenuated "alert" function to sandboxed code which does something slightly different than the real "alert". What kind of apis could the browser provide to safely allow such extensions/apis? Do these need to be standardized such that different sandbox vendors can interoperate. Client side sandboxed apps maintaining state and authentication. For example if a user is created in a sandboxed app how is it determined what that user can do? Create a standard for modifying a sandboxed environment Deprecate and discourage standards which ambiently or undeniably pass credentials. Create a standard for authentication within a sandboxed environment (maybe interfacing with existing auth without passing creds like 0Auth works)
