Opera Unite - Browser and Server in One

Opera has released a new version of their browser that includes Opera Unite -- a server that sits on top of the browser itself.

So what’s the big deal? Why would you want your own web server on your local machine? For answers, you have to go back to Tim Berners-Lee’s original vision of the web — it was supposed to be literally a web, rather than hub-and-spoke network of servers and web browsers that we have today. The advantage of the true “web” approach — that is, I connect directly to your PC rather than both of us connecting to, say, Facebook — is that there’s there’s no third party involved, which means we all control our own data and aren’t dependent on a server.

I wonder what kind of data or service users would put on their own mobile web servers?
