[nznog] search engine that shows illegal downloads

Hi, just found this news article.. http://tvnz.co.nz/view/page/411365/711264 what interested me most, was this "search engine" that allows the federation to see "any illegal downloading in New Zealand" 1) Is this something Telecom has come up with :) (couldn't resist it) 2) How do they determine if its illegal, or not just someones home made video of Debbie does Auckland etc 3) How would this be possible? The third question is the most serious one, just wondering how there could be a search engine that showed this information? This would have to be implemented at the backbone level? -- Antonio Broughton
