ICANN's Board of Directors has approved a plan to usher in one of the biggest changes ever to the Internet's Domain Name System. Starting in 2013, regulators will allow websites to buy new Internet addresses that include common words or corporate brand names. Instead of the familiar website addresses that end in .com, .net, or .org, for example, there could be addresses ending in .Apple, .CBS, or .McDonalds.

Cooperative Linux
What is Cooperative Linux ?
For layman, Cooperative Linux means software which allows Microsoft Windows and the Linux kernel to run simultaneously in parallel on the same machine.
Technically, Cooperative Linux is a port of the Linux kernel that allows it to run as an unprivileged lightweight virtual machine in kernel mode , on top of another OS kernel .
It allows Linux to run under any operating system that supports loading drivers , such as Windows or Linux, after minimal porting efforts . An alternative to using a Linux PC is a free license of Cooperative Linux (coLinux).This Linux project is a new approach to getting the Linux kernel to run under Windows. CoLinux contains special Windows drivers, which allow it to run under Windows as a guest operating system with all privileges .
