BrowserCom

From Soft2B:

Create instant peer-to-peer collaboration between any two web pages using only a web browser and instant messenger service. With BrowserCom, browsers participating in a peer-to-peer collaboration session "mirror" each other so they are all showing the same content simultaneously. Any actions executed on a peer browser are propagated to the other peers, including form input, JavaScript, Dynamic HTML, Web Authoring, or simply following a link. Contents of any web page can be a point of peer-to-peer communication once BrowserCom is enabled at the page, bringing all the media and content of the web into the instant peer-to-peer communication field. Possible applications include sales, tech support, and teaching.
