Real Time Text progress and Accessible RTC document as a working group note

Hi all,

Just to update you all, we put the Real Time Text discussion on the 
agenda for WebRTC working group and had a very useful discussion at 
TPAC. Based on our discussion it seems that there are current 
implementations via polyfills that can be worked into WebRTC 
applications, or extensions that can be used if there are protocol 
requirements. Both may count as final implementations as they get closer 
to publishing their new spec.

WebRTC will review their current implementation, e.g how it is exposed 
in the WebRTC stack and how interoperability is handled regarding RTT. 
Our Accessible RTC use cases document will also be helpful to them. FYI 
- we also asked the WebRTC group if they are happy for APA to publish 
our this document as a working group note.They were positively disposed 
towards the idea and expressed that it would be useful to have it as a 
separate doc. [2]

They also stated that they will review our use cases and see what they 
can take to update their own use cases document with relevant items.

A request was also made for APA to review the related IETF spec T.140 
Real-time Text Conversation over WebRTC Data Channels. [3]

This doc specifies how a WebRTC data channel can be used as a transport 
mechanism for Real-time text using the ITU-T Protocol for multimedia 
application text conversation (Recommendation ITU-T T.140), and how the 
SDP offer/answer mechanism can be used to negotiate such data channel, 
referred to as T.140 data channel.

We can discuss this at our meeting on Weds.

Thanks

Josh
