I see the problem, you have mistaken YOUR goal for THE goal.

OUR goal is to be able to bring up some set of test machines for a short time, 
and 100% uptime isn't an issue.  Being able to bring up machines on whatever 
hardware is currently in burn-in, or sitting around, IS a goal, it saves us from 
having to keep a machine around just for that purpose. As long as there is such 
a machine, we have satisfied our hardware requirements, so we don't need a hot 
backup or the admin issues a cluster incurs.
