A while back I bought the domain cvsite.com with the idea of developing a site where people could create a structured CV and make it available to the world. The USB would be that you will be in complete control of access to your CV at all times. All contact would be anonymised, meaning that if and when you decide that you don't want people (ok, recruitment agencies) contacting you through the site, you can stop them.
I registered the domain a while back and have never found the time to do much more than a very wooly spec - basically the previous paragraph. I've now moved on to designing the data structure and the general layout of the site, but I still don't expect the development to move very quickly. If you're interested check back here regularly - I'll be posting updates as it takes shape.
