WordPress and WebRTC?

I’m pretty new to WordPress and I was wondering about WebRTC integration : user permissions, page integration…
I’m especially interested in chat communications (writing and audio, video is not my first concern).
At the moment the only available plugins are about video communications and use an external solution (service).

Does someone have already addressed this topic and would share some hint?

After some researches I came across two plugins using WebRTC :

• Collaboration, which is a simple integration of TogetherJS
• wpRTC which is not enough mature yet but look promising !
