Firefly is a new cool little JavaScript application that lets let you embed real-time messaging on web pages or blog and allows unfettered chatting and interaction ability for visitors. Here's how it works: With a click, users can activate Firefly, and type a message anywhere on their screen.  Other surfers on the same page will see the messages for a few seconds, and can contribute to an anonymous conversation.
