Reading some blog, I found YouOS: a web site … or an operating system??
From the YouOS site:
YouOS is a web operating system that lets you run diverse applications within a web browser. Small applications like sticky notes or clocks. Large applications like word processing, mp3 players, and instant messaging. Even better, it’s very easy to tweak an existing application or write your own.
- Persist: Do some work. Log out. Log in later from another computer. It’s like you never left.
- Centralize: Manage all your web services, files, and accounts in one secure place.
- Collaborate: Share files and apps through a simple, intuitive buddy list.
- Customize: Install apps written by friends or write your own.
