Agreed. I want to build things that collaborate over the LAN if the internet goes away. It seems like the hash-addressed function thing would be a pretty nice way to do that: no name resolution needed, just talk in terms of hashes to whoever's in range.

But all of the resources available for learning the language are funneling me towards using cloud hosted infra that won't be available if the internet goes away. For all I know there is a Unison-y way forward for my idea, but it feels like the path is obscured by a layer of marketing haze.
