iLife '09 - still no good way to share a Library between users

I updated an old post: iPhoto library sharing - the official Apple method. There's still no good way to share iPhoto Libraries between multiple machine users. The best official workaround is using a disk image, which causes backup problems (grrr, Retrospect!).

The problem is not iPhoto's. I believe it's the result of an ancient design decision in BSD Unix file sharing. It impacts all resource sharing between users, including iTunes, iMovie, etc.

I wonder if it's addressed in Snow Leopard.

I think XP/Vista may have a real advantage here ...
