Okay, well let me ask this, in general: SHOULDN'T this be an easy thing to do, perhaps via a simple checkbox in the Admin account controller preference?
"Share iTunes and iPhoto library among all accounts", or something like that.
For those who DON'T want to share these things, don't. Works as always. But in a multi-user household, where perhaps a husband and wife, roommates, etc. want to keep a single, consolidated iTunes and iPhoto library, they could? Easily?
Has this never occurred to anyone at Apple, or here?
