In more recent times (2008ish perhaps, would likely have been early Ubuntu anyway) there was some sort of audio forwarding, I don't know how it worked though. I remember one time sitting on my couch with my laptop but wanting music to play from my desktop because it had good speakers. So I ssh-x-forwarded rhythmbox from my desktop to show on my laptop, pressed play ... and the music came out of my laptop.
