Let's assume you have a yahoo account and want to post a comment on stackexchange.com. You just point your browser to the stackexchange.com url [i.e. user location]. Now you log in using your yahoo account as OpenID. The browser loads the stackexchanges's JS client that enables you to post your text. There is no comment-posting-protocol required between yahoo and stackexchange. They only have to agree on an 3rd party authentication protocol. If stackexchange extends its functionality, let's say with real-time chat (which they did), your browser will load the appropriate JS client the next time you load the page. All parties in the chat will use the same JS client under stackexchange's control, regardless whether people have used google, yahoo, or facebook to log in. There is no need to standardize anything that crosses stackexchange's servers. Now you want to make a comment on some blog at blogspot.com. You point your browser at the blog's URL and log in using your Yahoo OpenID. The browser loads blogspot's JS client. The GUI looks quite different but you can post your comment as well. With the current RTCWEB thinking, we would have to specify an intra server protocol that covered stackexchange's discussion and chat systems as well as blogspot comments. Such a protocol would soon get very complex. > You should talk to ekr who's writing the security draft and see if you can > merge some of these ideas into it. > > I don't think it in any way helps our signalling/SDP/etc discussion, my > apologies. > Thanks for reading and commenting on the draft!
