Campfire

What is Campfire? I found this in the web 2.0 awards site. There are many interesting ideas to look at.
Campfire is a web-based group chat tool that lets you set up password-protected chat rooms in just seconds. Invite a client, colleague, or vendor to chat, collaborate, and make decisions. Link to a room on your intranet for internal communications.
This is a great tool for large business' etc. Check out the link for yourselves.
