We've been using Breeze Live for a few months now (and using Breeze for over a year for some specific applications). Here's a very interesting article on one person's specific experiences with Breeze Live:

Over the past couple of years, I investigated whether to use web conferencing software as part of my business. While I was excited by the potential, I weighed whether the costs would outweigh the benefits for my small company. The opportunity to try Breeze Live gave me compelling evidence that such a technology is a necessary part of my business.

In the following sections, I explain how I used the Breeze Live trial to deliver the following communications:

• Ten, two-hour developer seminars
• Six client meetings
• Three conversations with my remote developer teams
• Two conference talks

There's lots of good and useful detail about organizing and delivering, what works well, and how to make a successful presentation.

There's also a terrific checklist for presenters:

Preparation Checklist for Presenters

1. Turn off the screen saver in presenter machine.
   
2. Set the screen to a low resolution (such as 800 x 600).
   
3. Clear and organize your desktop.
   
4. Shut down non-essential applications (including IM, MSN, and so forth).
   
5. Turn off your telephone. Close your door and hang a “Do not disturb” sign on the outside.
   
6. Start the applications that you will share.
