Running Headless W/ OpenGL under X11

I use a number of machines during the day including four, a windows workstation, a linux workstation, a mac mini, and a mac MacBook Pro. I know, in this day and age, there are a number of ways to eliminate boxes. I can dual boot or run VMs, but there are often times that I…
