    One of the considerations that we in turing have 
discussed is electrical power: our plan is to have 
equipment available but not always on, rather mostly 
off, to be used for a few hours each week as part of 
a regularly scheduled class. 
    We've also looked at low-power machines such as 
ARM- or Atom-based systems. It seems good to have 
one machine capable of supporting VMs (Linux KVM) 
and one or two other machines that can serve as 
hosts on "other" LANs. 

    Note that working in a classroom allows more 
people to participate in the physical aspects of 
learning along with the convenience of the use of 
a projector and whiteboard at hand.
