I am a die-hard iterm + tmux user and often have many login shells open spread across many iterm windows/tabs, tmux sessions/windows/panes, etc.

I was tired of dealing with the pain of ssh-agent so I wrote some bash scripting that caches the agent environment, kills any extra uncached agents and automatically "attaches" to the cached environment so you don't have to type your ssh key passphrases in over and over.

Feel free to contribute, also feel free to talk trash :)
