Hope someone can help here. In our home, my wife and I have a Macbook Pro each, my wife has an iPad and we both have iPhones. My devices are registered under my Apple ID and my wifes under hers. In our company, we have two iMacs and they are registered under a completely seperate Apple ID. Basically, what we want to do is store our music on one system (possibly running FreeNas but not yet sure), and then share that library with my iTunes and with my wifes iTunes account. We then want to get iTunes Match (on each Apple ID) to access the music on our phones, etc. My questions... 1) If we have a central iTunes library that is accessed on both MBP's, is it possible to use the iTunes library on more than one iTunes Match service? 2) If the above is possible, is it possible to access the iTunes Match content on the iMacs in the office even though they have a different AppleID (i.e. can you use one AppleID for the 'system' and a different AppleID in iTunes)? I guess the only issue might be that if we buy apps from the App Store, we'd need to log in with the AppleID for the company.
