This is what they say it does:
"blinkx reads what you have on your computer screen and automatically links you to related information – Web sites, the latest news on the Web, even documents and e-mails on your own computer. For the very first time, blinkx 3.5 offers users fully integrated search and a true single click search experience."
This is loaded on the personal desktop, which may not be as good for an enterprise roll-out. This has some good promise though. So I will look into this and follow-up on it over the next week.
