Can/should conversations be used to keep track of a logged in user (traditionally done with a session). I was thinking of the case where a user signs in and a new conversation is started. This would effectively be the "root" of the conversation stack for the lifetime of the user's interaction with the application. So, this would also be a fairly long running conversation, and should be able to have non-transient entity references in it..

No, you should use the session scope.
