About:
Plan 9 was born in the same lab where Unix began. Underneath, though, lies a new kind of system, organized around communication and naming rather than files and processes. In Plan 9, distributed computing is a central premise, not an evolutionary add-on. The system relies on a uniform protocol to refer to and communicate with objects, whether they be data or processes, and whether or not they live on the same machine or even similar machines. A single paradigm (writing to named places) unifies all kinds of control and interprocess signaling.

Plan 9, a network operating system, that we should all learn from. It exploits the true advantages of communication. Using remote hardware or even remote Internet connections has never been simplier.

One protocol for all everything is the way to go. In Linux you have many individual protocols to be able to access individual things over a network. Like for graphics you have the X Windows protocol. But what about sound? Now you need another protocol for sound! This starts getting complex and insane.

Using Plan 9 makes you appreciate organization. It puts the system in operating system.

As far as I can tell Plan9 license is not listed on www.opensource.org. Is it going to be OSI approved?

Before anyone corrects me, the question may have become obsolete since OSI has finally started to do something about the license issue. See http://plan9.bell-labs.com/hidden/osi-diff.html.

It is approved by OSI, FSF and Debian Free Software Guidelines. The license now grants and forces more freedom than GNU GPL which is great.
