How to co-browse a website with my friend? What do you recommend?

[jstone]

Is there a special add-on or an application, possibly web based, that I could use to co-browse websites with my friend? So that I could see the contents of my friends screen, when he's surfing the web.

I'm not sure about add-ons or applications, but there's this web 2.0 site called Screen2.com (http://www.screen2.com/) for collaborative browsing. I've used it couple of times and worked fine.
