Might want to check out js8call, great for emergencies. Great propagation, supports async communications, as well as bouncing through nodes (every client can be a repeater). Bandwidth isn't great, but it can be a robust way to get a message across a decent chunk of the planet with minimal power.
Thanks! It's more ham-specific than I had in mind, but always willing to add another bookmark to the list.
