Since this has turned into the Warden thread, I thought I'd pass along another advantage to hardware multiboxing, but it applies when the hardware is only used for Warcraft. It doesn't matter what Blizzard can do with Warden, the only information they can collect off the computers is data files from - Warcraft.

I'm convinced Warden wasn't added to combat Cheaters, Hackers, and Farmers, but to give corporate security divisions an honest reason for saying "No, you may not install Warcraft on your company owned computer. It might send up corporate secrets to Blizzard"
