Wetzel,
Thanks for your posting, yeah interactive of youtube has been something I have been thinking about. Until the team is able to get a low-cost camera such as a flip camera ( less $100), I plan to used youtube and a survey tour to bring "interactivity".......

If you are a student on a team, feel free to fill out the survey if you like.......
Cheers,
Marcos.
