[pseudonym]

I use it for just about everything work-related, but given that my day job is literally "connect to sets of remote servers and bang out code" it'd be insane not to. Some of my coworkers still use screen, but tmux + wemux having the automatic "scale to the smallest attached screen" + "automatically follow the driver in pair mode" means there's a lot less "can you shrink your window"/"which window are you in now?" types of interruptions.

Apart from that, I've got a perpetual tmux running on my linode for irssi, and I've also got tmux running locally-- being able to set up multiple sessions connected to the same tmux server means that I can have a different tmux session per physical monitor, which means both a shared tmux copy/paste buffer and the ability to easily flip from window to window depending on what I want on which monitor. Ctrl+B for the local tmux, Ctrl+A for remote tmux means that there's no weird double-control-characters necessary. Add in some sneaky scripts to symlink login SSH agents to a known location that's exported to all tmux sessions for ease of git and you end up with a really clean overall workflow.
