As I see it, RTCWEB has a goal to enable audio, video and data 
communication  between a user in Website-A and a user in Website-B.

Sometimes I have seen in the discussion that we shall not build silos 

To me, that means create and use standards for the features of common 

Video, real-time text and audio are the three real-time media of common 
All three are possible to transport as you like, but the RTCWEB activity 
is about making it in a similar way to enable interoperability and ease 
inclusion in web applications.

Even the isolated web designer who makes the dedicated site only 
offering communication between users of that site and the customer 
service will be glad to find common ways to include the three real-time 
communication modalities as components rather than being forced to 
invent everything again.

And users will be happy to find that it works in similar ways in 
different sites. ( just as you are happy to find the gas pedal located 
in the same place in every car )

There are more reasons why standards are good for this purpose, but I 
stop here. We had a discussion in November - January. It just popped up 
again because of how interop plans with SIP were expressed in the "No 
Plan". And it was not the "No Plan" itself that was limiting, it was 
rather the way the need for legacy interop was described in the No Plan 

My conclusion is again: whatever transport we select for Real-Time Text 
in the WebRTC environment, there is a need to standardize it.
