This sounds to me a lot like the "Flash" scope of RoR and family. Though conversations don't look very heavyweight to me, a flash scope could be nice in order to remove any need to use that "conversationId" (or cid as it is in cvs) parameter. That segues to a minor gripe of mine, namely the conversationId parameter in the URL: would it be feasable to put the conversationId in a hidden formfield and/or the viewstate instead of the URL?
