The keyring stuff essentially allows you to associate arbitrary BLOBs with processes via a simple kernel interface. OpenAFS could store the credentials in a session keyring and all processes in that session would have access to the credentials. Then OpenAFS could just run a key search for the credentials when it needs to perform operations (Such as passing them to the server) with them. It's very fast, simple, and well designed

This is encouraging. How closely do the semantics of "session keyring and all processes in that session" match those of PAGs? (Group membership inheritance across fork/exec seems pretty clear; sessions have always seemed a little fuzzy to me.)
