Lately I've been wishing Signal had a bridgefy type mesh mode that enabled operation peer to peer over wifi direct or bluetooth, either directly or via a mesh of such devices. First I think it would be useful at protests, to preserve privacy (and whatever side of the political divide you are on, I hope we agree that covert government surveillance and tracking of people at a protest is wrong, here, in HK, or wherever). But it would also be nice to have when outside the reach of cellular or wifi internet. Think camping, traveling, people living with intermittent power, or those who lost power in some sort of disaster or emergency. I'm honestly not sure if this would be feasible, as I don't grok the signal protocol fully, but the signal protocol does support async messaging.
