My primary goal is to use a Mac Mini without a display as a music server - directly connected to a DAC - in one room. My secondary goal is to use it to stream to ATV in another room in the event that my primary computer is unavailable. Having a backup of my iTunes library would also be nice. I'll be using screen sharing with my main computer to manage the Mini as needed (like when there is a software update), but I really want it to be as low-maintenance as possible. Things that I've already figured out that I should do: 1) Auto login to the account that is running iTunes 2) Auto-start iTunes upon startup 3) Anything else? My questions: 1) If the Mini is only used as an iTunes server (no email or web browsing), and if the Airport network is secure, are there any security concerns if I am not using a password on the Mini? 2) Is there a way that I could use an iOS device to monitor the status of the Mini - i.e. make sure iTunes is still running if I am having a hard time connecting? 3) Is there an easy way to automatically synch the iTunes libraries between the Mini and my main computer? I'm slowly re-ripping my cd collection to ALAC, and it would be nice for my new lossless files to show up on the Mini without having to manually add them. Thanks in advance for any advice!
