The networked actor-model bit & CapTP goes back to E originally[1]. The other contemporary real-world protocol based on this design is capnproto rpc[2], which has implementations in several languages including both Haskell (of which I am the author) and Python. The ergonomics of the Haskell implementation could use some work IMO, and I've got some ongoing refactoring work on a branch. But it does work, and folks are using it.
