I remember the MBONE. I was working at a National Lab, and had an SGI Indy workstation with an IndyCam, so I spent some time setting it up.
One day I forgot to close the app when I left for the day, and came back the following day to a NastyGram from Van Jacobson, chastising me for using up bandwidth with an image of my darkened office door for 16 hours.
Good times.
