I actually thought about building this but shyed away due to not wanting to handle hippa and being a one man shop at the moment. Good to know someone tackled this.
It's quite a large project, so kudos to anyone who can do this as a one man shop :) We're trying to offload the heavy lifting of logistically connecting to the gajillions of health providers (via OAuth/proper channels aka SMART on FHIR connections) so that engineers can build the functionality patients could benefit from!
