I've been through the papers, and here is what I understood. Just to be sure I don't include erroneous data, could you please confirm (or oppose, but then please explain :) those assertions: - from the OSI point of view, the layers 4, 5 and 6 have a custom protocol implementation: 9P. - 9P offers an interface at layer 5 (messages, local) - 9P offers an interface at layer 6 (RPC, local) - a service does translation from 9P to TCP for external communication (at level 4?). Where does IL fit in all this? Hmm, still a bit confused. Sorry if the question seem a bit lousy, and thanks a lot for any help! Best regards Jef
