Modification to family tree

Ok so I just joined facebook, so a modification to the family tree idea is to create a layer on top of facebook to leverage all the facebook activities but still create a family tree organization on top. Maybe someone has done this, but I'm new to facebook so I have no idea.

Online 401K administration

401K's for small businesses under 10 employees are pretty much impossible to find. They cost around 2K which is quite a high cost.

An online self service application that would link to external accounts (schwab, etrade etc) and payroll or bank systems (ADP, administaff etc) that would let small businesses do self service 401K's would do extremely well.

iPhone application to find stolen iPhones

Only one application can run at a time on the iPhone so you cant leave it running in the background. Create a fake phone dialer/contact etc application that checks to see if the phone has been stolen if so, log the GPS based location. Open the default application.

Once the thief makes a call or otherwise uses the default apps on the iPhone, their position gets logged.

Mass Customization - clothes

Have people submit pictures of themselves semi nude, front view, side view etc. Let them upload the image. Let them enter height and any other important dimensions. Run an algorithm that can calculate all their important dimensions from the image. Don't save the image, but do save an outline of the person.

Create a customization XML standard that let's clothing manufacturers create custom clothes for people based on this profile.
