Hi 420,
I like this idea too, however getting 100 Bitcoiners in one place that are all willing to do this would be somewhat challenging. Perhaps the only place this could happen is at the Bitcoin conference next weekend. Are you going? I wouldn't mind trying to get together some people to go do this and raise awareness. All media outlets should be notified beforehand too so that it gets as much press exposure as possible.
exactly right, notify media beforehand. ad campaign, blah blah
i didn't get to conference
san diego may be a good place, there'd be 100 people there now just to get them to know about this
