Let the users design the meeting?

After reading this press release about how the DIY (for "Do It Yourself") Network is setting up a "blog cabin," where anyone can vote on design elements from countertops to fireplaces for an actual log cabin to be built in the Smokies, I thought it would be a very cool experiment to do for a meeting as well. Why not give all the options, from formats to speakers to room sets, and put it all out there for a vote? At the least, it would give you a better handle on what people actually want, versus what you think they want.
