This is a minor discovery regarding a venerable application, but I thought it was a great feature. I have used iPhoto Buddy for some time to organize multiple iPhoto libraries. Recently, I started to store libraries on a drive mounted on my Mini. Then, from my PowerBook, I would mount these drives via the network. Of course, this had to be done before I Option-launched iPhoto '05 to select alternate libraries.
iPhoto Buddy did away with all these intermediate steps. As long as I am connected to the host network, I can launch iPhoto Buddy and it will mount the network-attached volumes, and list the libraries that I have added to iPhoto Buddy.
