One possibility would be to include this support in the pmud utils to create a more generic hardware monitoring daemon. Since I would hope idle-time and overheating would be mutually exclusive, it shouldn't be too hard to add in a modular fashion. Perhaps I'll revisit this if/when these other features and implemented. -m
