I spoke with Nikolai Roth from zweitgeist at the CeBIT in Hannover a couple of weeks ago.  He showed me their product called Weblin, which is software that enables people on the same web page to see and communicate with each other.  While you are surfing, you and others on the same web page are visible to each other as small avatars and you are able to interact and chat with each other.  The idea behind Weblin is to make the Internet come alive and create the largest virtual world of all.  Nikolai filled me in on how Weblin works and what kinds of features are available.
