Perhaps you could put this post in another forum like "Non-Technical" of "Lounge". I don't normally visit the polls forum. You might get more replies in another forum.
I also thought of the same idea as you yrs ago, but never followed through with it due to not really having the proper equipment to do it and I'm not able to travel to all the various events.
However, I think's it a good idea. I think more people will be intereseted if they can see a sample of a finished product. There should be lots of private footage of SC events from the past. You might offer a free or discounted DVD of your finished product if people submit material that you end up using in your finished product. There is some limited multimedia footage of stuff on here, but would be nice to have a quality video product to watch. I kind of envision something similar to some of the car shows on tv/cable where the host goes to car events shows cars and interviews people. Would be cool to get inside Ford and interview people that had hands on with getting the SC designed and produced. Good luck
