Can you broadcast your Desktop?

[Knapp]

Hello,
 I want to be able to broadcast what is on my desktop. I want to do
one to many. The idea is to let others watch me work a program
(Blender3d) so that they can learn how to use it and at the same time
they would ask me questions over IRC. Being able to just prodcast the
Blender window would work just fine also. All I can find are things to
broadcast videos or video or to make still shots of my desktop.

Thanks.
