I stumbled across the Park City webcam site this afternoon. It's bloody clever - you can pick a camera and control it in 40 second bursts. If nobody else is waiting, you can control it for about 5 minutes. There is just one question though : Cam 1 is placed over the ticket line, and people do tend to get their credit cards out early. Waving them around under a controllable webcam isn't advised, because this close, I was able to screengrab the front and back of a girl's card. The card number, her name and all the info was easily visible, and the signature was big enough to print out and reproduce.
Technology is great, but this particular application might have been thought out a bit better.
