Different protocols ... Harald's only stipulation is that the protocol shouldn't prevent anyone from creating a centeralized conference control facility. The distinction I see between centralized control and distributed control is with centralized control, I must have a way to establish trust with the control facility which I must trust to authenticate all other participants in a similar fashion. With a distributed mechanism, I must establish a trust relationship directly with each participant.
