Simply plugging in a device can potentially be a threat, Moose. I don't
know how realistic or severe at this point.

Having dealt with a significant infection problem with students' USB sticks
before Microsoft wised up and turned off autorun by default, I can imagine
the mess that could be potentially made of any school network by a problem
like this one. It's virtually impossible to get compliance from all
students, and they're incredibly good at connecting devices unobserved in
order to do what they want.
