I just got a frantic call from one of our undergrads.

The classroom computers don't have a new enough version of Quicktime to let them use the campus cable system (DATN) to watch the Superbowl in one of the classrooms. We don't control the classroom computers, and there's no one in the computer center today who could do an update for them.

They were going to use one of their notebooks, but DATN is firewalled off from the wireless system.

The solution: I have the web address for the DHCP server on my computer, so, from my living room (where I'm playing Civ4 and watching the Superbowl), I set one of their notebooks up to use the wired ethernet, and, a reboot later, they've decided they really owe me, as the game is now coming in over both projectors in the big classroom.
