This may be a bit off-topic, but I'd like to know if there exists a good utility/app that will allow for remote shutdown/powerup via IP (kind of like wake on LAN). In our museum install, we have a seperate AV system that is networked to the G5 cat servers and they have such a function for their WinXP boxes using Depicus software. I just can't seem to find something like that for OSX.
I'd rather not have the cat servers running 24/7.
