After I upgraded my desktop and netbook with ubuntu 9.10, I started playing with their new Ubuntu One service. It allows you to share files across multiple computers over the internet, with automatic syncing. So, I created a folder called slideshow and shared it. I can now add photos to this slideshow from any computer and it syncs with all of them. How do I use this in a real world situation? A community photostream for digital picture frames. I don’t have a digital picture frame, so instead I configured the screensaver on my netbook to read from this folder. Now I can share this folder with close friends and they can add pictures which automagically start playing on my screensaver.

This could get interesting if this becomes mainstream. Imagine it being used in an office enviroment where employees can upload photos and their streamed on the walls at the office.
