Proliferation of my profile

Today my social profile is distributed and duplicated across multiple social networking sites - facebook, myspace, twitter, orkut, xing,... the list is endless. I don't think I will be able to keep them all synchronized and up to date. However, it is still only my social profile, so I guess it is not earth-shattering.

But imagine how it would be if the same were true about my professional profile. If a potential employer sees different versions of my resume (which is the same as my professional profile, or should be, in my opinion) on different sites, what would she think?

What I need is a place to store my single definitive professional profile and a way to control access to it tightly. I must be able to say "Here is my latest resume. You will be able to use this link for the next 3 days to see it. By the way, I have hidden some of the information that is not relevant at this stage, so if you need any other information, let me know". I must be able to pull the plug on the link even earlier if I want to, or I should be able to show more information under the same link, or even have it password protected. That's the kind of control I would like to have over my resume, to start with.

What do you think?
