I love this idea! I work in an open space with a bunch of developers in close quarters, and we're constantly interrupting each other. The collaboration is great, but sometimes it would be nice to be able to get some uninterrupted time to really get stuff done.<p>My only concern is that the sign always says "Wired in" even when you aren't wired in. I know I could teach my co-workers what each color means, but I would like it if it was a little more intuitive. What are your thoughts on how to get your co-workers on board with this idea?
