My wife and myself have separate accounts on our Macbook and I was wondering whether there was a way of sharing the iTunes and iPhoto library between the two accounts.
Have a look at the Home Sharing feature. Not sure if it will work on the same Mac but it might if both users are logged in. Alternatively, keep the library on an external drive.
I tried the home sharing facility and it happily finds the iTunes library on my iMac from both accounts on the Macbook, but it doesn't find the iTunes library on the other account. When you switch accounts it seems you automatically log out of the other account; unless there is a tweak to keep both accounts live.
