Do you have any examples of this approach?

I'm actually taking the time to hash out the details to do this as a side experiment project, but basically what I read this project as showing is that if you leverage asynchrony you can let agents be more efficient - and you get this "for free" if you model your "agents" as actors that interact with the system through message passing. Then all the system operations become messages to different actors, need to read a file => message the fs actor => get reply from FS actor as a message when it's done. You'd probably need some out of mailbox ways to share blob resources and sockets for realtime (audio), but for the most part simple message passing should handle most of what LLM agents do.

Actors can have identities and roles for RBAC, etc. you - cross agent communication is the same as sending any other message to a actors.

Not to mention that actors can be on your device, another device, etc. whatever the router can resolve - it's transparent to the agents.
