Another business idea you are free to steal … paying famous people for their time. Let's say you want to talk to P-Diddy, Bill Clinton, or Warren Buffett. Pay them for their time.
I'd like to see a business with a directory of famous people who all have a rate per hour that they have specified (kind of like what Ether does with knowledge professionals). Then, through the site, you can schedule a time to talk to your favorite person by phone. Would it be worth it for you to pay $1000 for 30 minutes of Sean Connery's time? Maybe. Maybe you have something to pitch him … or maybe you just want to ask him an question about what it was like to be James Bond.
And it could be an interesting academic, a great researcher, or someone you want to talk to about roofing.
Regardless, for the famous person it could be fun, easy to schedule (could do it while in the car or at a convenient time for them), and could be a good side source of income (and the target could decide to donate all or part of it to charity).
