I found a a great article by Pivotal about how they use tmux recently <a href="http://pivotallabs.com/how-we-use-tmux-for-remote-pair-programming/" rel="nofollow">http://pivotallabs.com/how-we-use-tmux-for-remote-pair-progr...</a> Anything else amazing that I'm missing?
If you are a Linux console lover like me, I have a tool I've been working on for a while: Termbeamer (termbeamer.com). The win over screen/tmux is that it is much easier to set up (especially if you are behind NAT or a firewall).
