How would you like it if the roles were reversed and we couldn't agree on
an MTI audio? Would it be acceptable to "simply drop the audio" and let the
participants mime their way through the call? The entire reason I'm
starting a WebRTC video call is because I want video. Otherwise, I'd pick
up the phone.

It works today.  Sometimes skype and hangouts offer video, sometimes only
audio.

> Also, offering users "advice" about choosing a browser is also a
non-starter. If 3 people join a call with IE, Firefox, and Chrome
respectively who is on the "right" browser? One is not necessarily better
than the other, other than we need them to agree on a codec. Some people
may not have the necessary permission to switch browsers (work). Others are
very touchy about their browsers. Asking them to switch isn't going to go
down well.
