I spotted that recently on allaboutiphone - a cool iphone site, (no affiliation) and yes, it is a cool service - however it still relies on the "scraper" being honest - it is more of a reminder - kinda like when someone rightclicks to steal, me walking up and shouting "Oi copyrighted" (in my head it has a sarf London accent) and the reporting feature of it is interesting, it sends back a report everytime someone highlights some text on your website - the downside is that, and in firefox it will keep clicking. www.allaboutiphone.net Or as an ex-client of mine once suggested "..you can just disable right click.." (note, that last one wasn't a serious suggestion).
We have been looking at site scanning type tools to find duplicate content, but I don't believe anything effective will come along anytime soon, we may have to develop something in house if we are serious about it, at the moment just putting out the smaller fires is the most cost effective solution ...
