Fascinating. I like the idea -- I'll just have to try it to find whether I can rely on it [my past experience with radioSHARK software's updated version suggests caution with Griffin software].

I like the look of this bit, which might be useful to me:
" * Trigger when computer will sleep (checkbox): Generate a trigger just before the computer enters sleep mode. Your tasks have a maximum of 30 seconds to execute any tasks before the computer will sleep.
* Trigger when computer did wake (checkbox): Generate a trigger just as the computer wakes from sleep.

***************
Values

* IsSleeping (number): A non-zero number indicates the computer will begin sleeping. Otherwise the computer is waking from sleep.
* State (text): The name of the sleeping state of the computer when triggered. Values are 'Sleeping' or 'Waking'. "
