Mosh is not at all like ssh, tries hard to avoid duplicating ssh functionality, and this is by design.

If it were like ssh the authors would have had to then handle security/authentication and all that jazz perfectly. It was written to "stand on the shoulders" of ssh, except handle terminal emulation and UTF-8 correctly. By using ssh, you don't have to trust "some new thing" as long as you trust ssh.

It's not even a shell protocol if you think about it!

Mosh bidirectionally synchronizes the state between the terminal window on the client and the virtual terminal on the server. It runs at a frame rate, which results in not filling intermediate network queues, which is where the low latency comes from. :)

Nor is SSH. Feel free to take a read over the RFCs. There's next to no 'sh' in SSH as a protocol. What mosh adds to SSH is the ability to securely resume a session. SSH is fundamentally protocol for setting up a secure connection and then ping-pong messages back and forth.

tmux runs locally. It's not a network daemon. The complexion of a daemon and protocol meant to operate over a network is very, very different from one intended to run over Unix domain sockets or on the loopback interface.
