While the idea of an Internet-based operating system has already been explored through offerings such as YouOS and EyeOS , Xcerion, a small Swedish company, is taking an ambitious new approach to the idea. The company’s XML Internet Operating System/3 Beta (XIOS/3) is best described as a “Cloud OS” and Web 2.0 service. I’ve been testing it on a Windows machine, loading XIOS/3 in Internet Explorer (you can’t yet load it in Firefox), and it generally looks promising.

XIOS/3 has many of the properties of an operating system (though strictly speaking it is more of a Web-hosted environment), and is targeted at online application development, collaboration, and sharing of free applications. It is XML-based, and uses AJAX to connect to back-end servers. If application developers begin to collaborate using it, it could become a promising new open-source platform and a flexible way for web workers to get jobs done.
