Scoopt is coming up with a syndication service that collects info from digital camera users around the world in order to sell it to the press and let users participate into it:

"Virtually everybody now has a mobile phone, and virtually every mobile phone now comes with a camera. Britain on Britain supplementThis means that somebody, somewhere is in a position to photograph just about anything that happens on the planet.

If you photograph a newsworthy event, you could have a valuable scoop on your hands. "

I would not bet on the chances of such a service - first it needs huge visibility in order to catch real scoops and second it needs to act very fast sorting out the needle in the haystack.
