Google Health has launched

From the contract you have to agree to:

When you provide your information through Google Health, you give Google a license to use and distribute it in connection with Google Health and other Google services. However, Google may only use health information you provide as permitted by the Google Health Privacy Policy, your Sharing Authorization, and applicable law. Google is not a "covered entity" under the Health Insurance Portability and Accountability Act of 1996 and the regulations promulgated thereunder ("HIPAA"). As a result, HIPAA does not apply to the transmission of health information by Google to any third party.

And it’s still solving the wrong problem.
