I think you've misunderstood the desired overall configuration.

There's only one laptop in the system, as I envision it.  The cluster is a 
sealed box, connected by a "wire" (e.g. a network cable) to the one laptop, 
which runs Windows XP.  There's one "Big red switch" on the cluster box 
that turns it on and off.   (well.. you might want a few switches.. one for 
power, and one for reset, although, with diskless nodes, it's not clear 
that power cycling isn't as good a way as any to reset the nodes)

i.e. there's no CD ROM drive on the cluster nodes.. they boot off the net.
