App to take photos and instantly stream as slideshow to Apple TV?

[Taustin Powers]

I'm getting married this Friday, and my wife-to-be just had an interesting idea for the party. We'd like to have my sisters' kids run around and take random photos with their iPod Touch, and have those photos instantly appear on the big screen via Apple TV as a slideshow. So the photo collection for the slideshow would grow as the evening goes on, but all the kids have to do is take more photos.

Anyone know an app that does this?

I believe you could do this with the built in Photostream.
