I have a link to a flash site PTC created a long time ago, but I am not sure it will be of any use to you. Here is the link just in case.

If you have a fast Internet connection at the meeting location, you could show this mini site to the users. I would recommend you go through all the areas of the site before the meeting in order to have them in memory. This will prevent the slow upload of the videos in each section.
