Does anyone know if voice traffic actually passes through super-nodes, or are super-nodes just used for authentication, and punching holes through NAT? If it does, can you point to a reference stating this? Yes, Skype traffic does pass through supernodes. I know people working on using Skype to route around censorship and supernodes allow you to connect two clients even if the direct connection between them is dropped. Here's an article in Skype about rate limiting if you're running as a super node which is further evidence that voice traffic does pass through super-nodes. http://forum.skype.com/index.php?showtopic=13780 http://forum.skype.com/index.php?showtopic=13780
