If one had a group call (perhaps with video) and during that call many participants had bread, could they make a zimun together?
I know that you only need to be within earshot to answer for a zimun, but what if you were never together in the first place. And does the internet count as within earshot?
I'm guessing it could be ok, because you have had a meal with eachother, though not physically. If strangers had a meal together physically, they can't make a zimmun - seemingly the meal conversation matters more than their proximity.
