I just though of an interesting way to make photography easier at really busy locations.

Let's say for instance that you want to make a poster featuring a really cool looking castle that you're currently visiting. The only problem is that there are way too many people in the way. The castle looks like it's at Disney World (with all the tourists) instead of the Middle ages. It's unlikely that you'll be able to take the photo at a time when no people will be in the shot, and editing all those people out in Photoshop would be difficult.

The solution is to get your tripod out and take the same photo mutiple times over a period of a minute or two. With any luck, people will be moving around enough that you'll be able to edit them all out of the scene without having to "make up" parts of the photo.

The editing is much easier than normal. Just put all the photos into Photoshop as separate layers. Make a selection around the person you want to remove and then and then just delete holes from the layers until the person is gone. You don't even have to be careful about selecting the people.

Does this sound like something you'd be interested in trying or is it somthing that's already widely in use?
