Use Campfire? Use a Mac? Then check out Pyro. We're big fans of the way it shows unread messages in the Dock and lets you drag and drop files into a Campfire chat room.
Your Campfire chats in a dedicated application, with the number of unread messages on the Dock icon, in Growl and on the Campfire tab bar. Drag and drop file upload. Accelerated room switching. AppleScript support. Pyro for Mac OS X 10.4 does all that, and is completely free, so download yours now!
