The Phoenix Framework (web framework for Elixir) already solves this for you.[1] It's called Phoenix.Presence. They used a combination of CRDTs with heartbeats to implement it. You are right, it is a hard problem because of the distributed nature of Erlang/Elixir. That's why Chris provided a framework level solution for it.

My Erlang Factory keynote also goes into the design considerations and PubSub layer optimizations that sits underneath Phoenix.Presence: [VIDEO]

There is a nice talk from Erlang Factory 2016 called "Making the Web Functional with Phoenix and Elm" [VIDEO]

I wonder if the same might happen to Elm, should Phoenix adopt it as their browser language of choice. There's definitely a connection there -- for what it's worth, the keynote at 2016's Erlang Factory conference was a shared talk between Chris McCord (creator of Phoenix) and Evan Czaplicki (creator of Elm), "Making the Web Functional" [0] [0] [VIDEO]

Speaking of Elm I liked this video from Erlang Factory about using Phoenix and Elm together. They both have a functional flavors so I think it might appeal to same people: [VIDEO] The first half is about Phoenix, the second about Elm. I don't know much about front-end stuff but I did like the Elm bit as an intro, especially the debugging and nice error messages part.

Chris McCord had fun implementing a CRDT in Phoenix.Presence: [VIDEO] (from about 17 mins by the looks of things).
