I'd use screen. Get your friend to start a screen session with

  screen -U -a -S myscreen

then log in to her machine and connect to the same session with

  screen -U -a -x myscreen

for this.

The -U (use UTF-8) and -a (use full terminal capabilities) are optional.

It's low bandwidth and you'll be sharing the same shell session. Screen 
also has the advantage that if you get disconnected, you can reconnect 
to the same session again.
