Ubuntu server

Opera Unite is a unique technology that turns any computer or device running Opera into a Web server. In other words, your computer (running Opera Unite) is truly part of the fabric of the Web, rather than just interacting with it, and it's something anyone can use. With Opera Unite, everyday non-technical users can serve and share content and services directly from their own computers in the form of intuitive applications.

It all happens through the browser, so no additional software has to be downloaded, and it will work wherever Opera works (Windows, Mac, Linux, and later mobile phones and other devices).

Opera Unite is now part of the Opera browser.
