[RTW] New proposed charter text. Please review before the BoF.

[Roni Even]

Hi,
I noticed that the proposed charter talks about communication between two
web browsers. Is the work limited to point to point communication or is
multipoint also in the scope of the work
Thanks

> There are a number of proprietary implementations that provide direct
