User runs `ssh-wrapper example.com`
`ssh-wrapper` does:
`ssh example.com /usr/bin/env sh -c "$(cat conductor.sh)"

Where `conductor.sh` is a sh script that does something like (pseudoterminal below):

echo <control sequence to notify terminal emulator that it's in ssh mode>
run login shell as a child process through `script` on file descriptor 3
while true:
  output = [read from file descriptor 3 without blocking]
  if output not empty:
    echo "begin-output"
    echo $output
    echo "end-output"
  command = [read from stdin without blocking]
  if command:
    echo begin-command-output
    eval $command
    echo end-command-output
  
The terminal emulator will have a mode that knows how to parse the "framed" output
and issue commands in place of the usual interaction between a terminal emulator and shell.
Furthermore, it can do file transfers, run `ps`, measure CPU utilization, kill jobs by PID 
when the user requests it, etc. to enable a fancy UI over ssh.

its UI.
