different implementations of what ? TURN Servers do not have to
interact with each other. The interactions are between WebRTC server
and TURN servers. I see it as perfectly OK if different TURN servers
access different WebRTC servers in a different manner. This WG is
about STUN and TURN; I do not think that we have to deal with WebRTC
servers standardization. I believe that the document addresses the
TURN server operations standard in a proper way, and leaves the
question of WebRTC to their WG.

How the TURN server stores the credentials, amd how those credentials
are getting filled in the database, is not the topic of this WG, I
believe.

Thanks
Oleg
