Opera, the Norwegian company that introduced tabbed browsing, page zooming and mouse gestures years ahead of the competition, now have a new string to their browser bow. It's called Opera Unite.

What they've done is add a simple server to the browser that allows users to host web services such as file and photo sharing, streaming media and chat rooms. The emphasis is on simplicity: start the Web Server application, go to the index page of your site-to-be and make it available -- either via Opera's own proxy servers or UPnP. To share files, simply point at the directory you want to share. You'll need an Opera-running machine to host, but any other brand of browser can browse your site.

Opera reckon that Unite with change the fundamental fabric of the web. It's certainly an interesting addition the cloud computing concept. What do you think?
