these programs are available for free on the Internet. The next step is

If
you want to go beyond talking heads on Ustream, Camtwist allows you to
change the virtual video device so that you can broadcast parts of your
screen, or broadcast videos previously saved to your computer. This is
a great tool that has a lot of potential for conferencing sessions. To
play the audio of a movie, playing iTunes or recorded mp3 audio while
streaming, use Camtwist and set the "General" preferences as
Soundflower (2ch) For more information go to this tutorial.
