Here's an idea, a firefox extension that let's you turn on a 'broadcast' feature that causes your browser actions to be posted to a remote server; where subscribers can 'follow' your clickstream in near real-time.
I wrote something like this back in the days before browsers reliably implemented cross-domain security models. I could see where each visitor on my site went in real time subsequent to their visit, chat with them, and redirect them to new pages. Enabled some interesting conversations.
Web as television.
