I believe the Dalas Semiconductor 1-Wire temperature sensors are the
typical solution for something like that. There's several available
libraries. You might check out http://www.brianlane.com/digitemp.php,
or google about. With a little scripting glue, it shouldn't be tough.

Assuming you can get this Shiva to work (Your best bet is the
Modem-HOWTO), there's several solutions for this. In a previous life,
I used a collection of scripts called "mon" to monitor services and
execute actions based on their status.
