Ideally, I want:
First choice: to shut the laptop lid and let it continue serving music. InsominaX seems to let me do this but I'm suspicious that it's messing up MinimServer.
Second choice: Let the display go to screensave whilst serving music, even if I can't close it.
Third choice: Let the laptop carry on serving music without going to sleep (Caffeine seems to allow this) but it doesn't seem ideal to leave the display blazing.

p.s. I appreciate this isn't a MinimServer issue, but I'm hoping that one of the MinimServer Mac users would have previously dealt with the problem.

I am primarily a Windows user. To achieve your third choice on Windows, I would set a screensaver of a black screen to appear after a few minutes of keyboard/mouse inactivity. Can this be done on a Mac?
