Fung talked with Computerworld about how isoHunt has evaded legal trouble so far, why he holds out hope of working together with Hollywood and the music industry, and how he's launched a new P2P site for just that purpose.

How did you start isoHunt? I was studying engineering and physics at UBC when I started isoHunt. I just wanted to learn some new programming.

Were you an active file-sharer? Not really. Frankly, I wasn't even using But I saw how potentially disruptive P2P was to the entertainment industry and content distribution in general. There was a gap in terms of a good search engine for file-sharing networks. Google was getting big back then, but wasn't yet on top. Neither Pirate Bay nor MiniNova were around yet.

How is isoHunt different from them? The Pirate Bay gathered the torrents that point to files and hosted them on its own servers on something called a BitTorrent tracker. A for content: it tells a downloader who else has the content you're looking for.

Pirate Bay also categorized torrents for easier browsing. Both BitTorrent trackers and categorization are touchy issues, legally. Because the law is all about intent, whether you are intentionally leading people to copyright infringement.
