Mobile IT Education?

SickKiwi asks: "A client, a local polytechnic, has recently asked me to come up with plans for a mobile IT bus to bring technology to rural areas. I would love to find out what other people in the field have come up with in the way of workstation layout, OS choices and Internet connectivity. There doesn't appear to be a huge amount of material available but as the technology gets smaller, mobile classrooms become more and more practical." What vehicles would work best for this kind of application? A converted bus? A mobile home? An 18-wheeler with a heavily customized trailer? What kind of hardware would you put in it?
