For sure do not go for this hybrid model, in the session I chaired all talks were live but I was ready to break rules and play any remote talk from my laptop (I had them loaded just in case!)... it made no sense to me to exclude folks! (I mean we had talks prerecorded and even had a zoom used for transcript, which I saw people using so I'm hoping it was useful!). P.s.
@cfiesler @sypark love the microwaves idea too, I would have used it :)
