Folks, May I suggest that we wind this discussion thread down. Whether correct or not, analyses of Khaled's character are probably not helpful and repetitive versions of them are less so. The S/N ratio on the IETF list is never wonderful and this thread should not contribute to making it worse. At least IMO, Khaled has been given a number of quite constructive suggestions (both on-list and off) about how to proceed if he wants to do so. Almost all of them include focusing on a problem statement and/or a careful and reflect literature review and analysis, but, if he wants to make progress, he needs to understand the details of those suggestions. Let's give him time to do that and see what, in the form of a draft focused on those topics, he comes up with and, in the process, try to reserve judgment about intentions, quality of listening, etc. best, john
