I plan on getting a used iMac to use as both a second computer as well as a music server. Believe it or not, after using Macs for 20 years, I have never had two functioning ones at the same time. I was hoping to get some suggestions on the fine details of doing what I want. I have my desktop Mac downstairs in my office, and plan to have the iMac in the dining room, which is between the living room and family room. Both those rooms have audio systems in them which I want to feed music in iTunes, which will be shared (Ethernet) from the main Mac. The first thing I'm looking for is suggestions on good ways to get the audio from the iMac to the two systems. Each system is within about 20 ft of the iMac, but in different rooms. I'd like a somewhat elegant way to get the audio to both systems, without spending much money or creating a mess of course. I was also wondering if there is any kind of "remote desktop" system with networked macs. What I would specifically like to do is be able to send and check emails from the iMac as though I were working on the desktop in my office. Meaning, I'd like to be able to see Mail on the iMac exactly as it is (received emails, accounts and so on) on the Desktop Mac. I don't know if this is possible. Basically, I want it to work as a remote terminal of my main Mac.
