I don't know about Lunatic, but there's a bunch of Rust actor frameworks that run on many machines. I think I saw one that supported moving an actors between machines
kay ended single machine. bastion and actix has examples of multi node cluster. wasmcloud is wasm also. riker and some other has no examples of multinode cluster
i am on search myself. seeking orleans like solution. bastion has cluster support. so may be it should be checked. cluster is needed for multi node and move. so for now i am coding raw redis, k8s pods, in mem cache and websockets...
For example, Kay https://github.com/aeplay/kay (used in https://aeplay.org/citybound)
I'm less sure about Axiom https://docs.rs/axiom/0.2.1/axiom/
And then there is Bastion https://crates.io/crates/bastion that I think allows moving an actor to another machine
