How about this:

- On all servers add the following to sshd_config:
    AcceptEnv MYPROMPT
- and the following to ssh_config:
    Host *
        SendEnv MYPROMPT
- fix shell rc files on servers and workstation:
    MYPROMPT=3D"$MYPROMPT>$USER@$(hostname -s)"
    export MYPROMPT

and you will get more than two hosts:
me@sys1>me@sys2>me@sys3:~%


We use this for root account to give every admin his own:
/root/.zshrc.<admin>
/root/.zlogin.<admin>
/root/.zhistory.<admin>
/root/.vimrc.<admin>
/root/.viminfo.<admin>
...

    Everything should be made as simple as possible, but not simpler.
