Paul, You asked me to repeat that: if not the telephone system itself- would Christian prepare an analysis saying "a Internet of `appropriate` capacity with RSVP and IPng would allow for concurrent AUDIO (as Jon said) of phone quality for everybody ..." The only problem I have with this phrase is the mention of RSVP. I don't think there is actually any major problem for providing a best effort service dimensioned to fit the needs of 600Mio internauts (or 6 billions, for that matter). I am convinced that some policing will be needed to make sure that usage is proportionate to investments (and subscription rates). I am however definitely not convinced that RSVP is what we need there. RSVP is about giving special priviledges to a few flows; we need to provision sufficient resources so that the average flow has adequate capacity, which is a different problem. -- Christian Huitema
