Hi Stephen,

>(2) WebRTC does not require STUN or TURN servers for some calls, even if it does for many. Why is it ok to require such a server be present in all calls (which I think this means) espcially 
>when that means exposing additional meta-data (calling parties in a case where the servers weren't needed and call duration in all
>cases) to those servers when that is not always necessary? 

Could you please refer to the text which you think mandates STUN or TURN servers?

If there are no NATs, the STUN requests can be sent between the endpoints, without STUN or TURN servers.

Regards,

Christer
