I've just published the first draft of the rxgk-in-AFS document. This details how rxgk is implemented within AFS, and contains proposals for handling departmental fileservers, migrating to rxgk, and for securing the callback channel. The draft is available from: http://www.ietf.org/id/draft-wilkinson-afs3-rxgk-afs-00.txt Please review and comment! Thanks, Simon.
