Do you really need a fake thing? cant you fake it in software and  
once the
temperature goes too high you just run a script which hooks into NUT and
sets the TemperaturUPS to NO battery or something and shut it down using
that? I was planning to use lmsensors to monitor the temperature and  
then
shutdown.
