Prevent sleeping when streaming from iTunes to Apple TV ...

Hi,

Streaming to the Apple TV from iTunes does not reset the system's idle time, so it does not prevent the computer from falling asleep in the middle of a movie presentation. Monitoring iTunes CPU usage with an AppleScript handler does not work either ... the CPU usage is not amplified when iTunes is streaming to the Apple TV ... gosh !!

I created a not so perfect work around. I use Caffeine that resets the computer's idle time. Being a manual intervention, it is not a perfect. I am still looking for a better one, in order to prevent these 2 problems:

(1) I would like to find a way (shell script ???) to detect iTunes/Apple TV's streaming activity automaticaly: this way I could monitor the computer's idle time; not requiring the manual intervention of activating Caffeine is basic ... you realize the importance of this when the streaming stops in the middle of a projection and when you have to go in the den to awake your computer because you forgot to activate Caffeine; it is more frustrating, if you forget that repeatedly;

(2) while streaming to the Apple TV, the screen saver should be activated without allowing the sleep process.

These 2 could easely be done by reseting the system's idle time when streaming. It should be a standard iTunes/Apple TV features, nor requiring any work around.

Well ... hoping this will help to bring a more perfect solution.
