Here is a quick-and-hackish way to stream / broadcast your terminal (http://www.commandlinefu.com/commands/view/6788/):

    script -qf | tee >(nc -l -p 5000) >(nc -l -p 5001) >(nc -l -p 5002)

The client can then run `nc your_ip port` to watch your terminal live.

Also, I once wrote a node.js script that broadcasts recorded terminal sessions. To see a demo:

    nc wei23.net 5000
