In the specific case of Emacs, assuming you're connected via ssh, sshd is running on port 22 of both hosts, an Emacs server is running locally, and emacsclient is in the default local path, a bash function or script along the lines of

  for i in "$@"; do
    ssh "${SSH_CONNECTION%% *}" emacsclient --no-wait "/ssh:$(hostname):$(realpath "$i")"
  done

should work.

For best results, use ssh-agent + agent forwarding to avoid password prompts.
