I'm not sure if you can force a Sun to have its console on the screen/keyboard if it doesn't have a keyboard attached. In fact, I'm pretty sure you can't.

On the other hand, there's nothing that requires that the console be the screen/keyboard to run an X session.

But it'd be harder to get to the console that way on all of the computers, especially the Windows machines. If his network went down, he'd have to temporarily recable everything.

Aren't you glad I'm here to answer your questions, Andy?
