Yes, I've got a mac mini still. It's connected to my TV, and it isn't the machine with all my pictures on it. I will see if iPhoto will let me synch the photos from my desktop machine in the basement across the network.

Question about using iPhoto as you suggest...

If I use iPhoto on the Mini to organize albums based on photos on the network fileshare, will it insist on writing back changes to those files, or will it clutter that remote directory with database/cache files and folders? Or will it leave the original files alone and keep its dirty little database and cache to itself?
