Before anthing else,
Hello I'm new on borad I'm french and I'm reading your post because P2P protocol intresting me.


I've already think of somhing tike that but it hold some problem like if your relay is shuing down. you must find a backup way but it could be long and you can wait when you tranfer voice.
even if voice with vocoding is only a 12kbit/s stream you risk with a tatly free communication to be overloaded (specialy on the relay level)
I'm continue to work on the subjectbut it looks to have no isues.
