This is amazing! We have spiders and robots to crawl and compile searchs for the web. Dogpile used to (and probably still does) have a search for major FTP sites. We have some (rather crappy but getting better) P2P search engines. Viruses that are tailor made to crawl the internet looking for specific data instead of destroying it was bound to happen. Provided you could keep the propogation controlled, people might not even know about it.

Imagine a virus that exploits a box, searchs for specific data, send it to you, patch the hole the came in with, and moves to the next computer.
