Odigo
In the pre-beta stage, but looks pretty cool nonetheless. It’s sort of like ICQ. However, it tracks what web site you are on, and while connected to the Odigo server, notifies you of other surfers who happen to be on the same page at that time. The intention is that if someone else is visiting that same site, they might have similar interests to you, and may know of other sites that you might not. Etcetera. It’s recommended you turn the program off when you decide to go porno hunting. Unless you’re into cyber-orgies and other unmentionables. Sorry, just had to throw that in. It’s just a little suspicious that the Odigo server has the potential to track your browsing habits.
