What about letting people use the personal mic they're already
carrying, i.e. a phone?

Interesting idea.

I wonder how well that would work in practice. Are all phones good
enough to prevent echo?  

Unless you get the latency for the WebRTC<->in room speaker down lower
than I'd expect it to be I'd expect echo cancellation to have fun,
though beam forming might reject a lot of in room noise including that -
higher end modern phones are astonishingly good at this stuff.  I'd not
trust it to work reliably for all attendees though, it's the sort of
thing where you'll get lots of per device variation.

The local audience should be listening to the in-room audio, in order
to avoid echo. Also, all local mics should be muted, if someone is 
speaking from a remote location. 

Yet, echo is unavoidable if a remote participant is speaking while 
listening to the audio without headphones. If this ever happens, I
guess the moderator should cut the remote audio and ask the remote
participant to lower their speakers or use a headphone.
