IPhone a Model for Feds

Technology Review carries a piece suggesting that an electronic health record system, sponsored by the government, should be modeled on the IPhone:

Their approach is modeled on successful IT products outside of health care, including the iPhone and Facebook, which rely on innovative applications from third-party programmers. Mandl and Kohane propose what they call a platform approach, in which EHR vendors sell a flexible, basic platform that is designed to work with components from other vendors, much as the iPhone works with applications made by a myriad of third-party developers.

I'm really out of my depth here, but it seems just a little facile. I'm not clear that either Apple or Facebook started out with the idea they were doing a "platform"--they did something, they made it open, and the snowball started rolling. It's possible a software package that established identity, privacy, and security, sponsored by the government could work. Indeed, in systems terms we already have a government sponsored system for identity (i.e. birth certificates, drivers licenses, death certificates, green cards, etc.) which is the basis for most of commerce.
