I generally favor a private non-profit solutions over a public single payer mess, but the conflicts of interest are pretty obvious (how many AWS cloud instances are required to support all the records?)
Also, this does nothing to fix the system (owner-agent conflict between insurance companies and patients, with the patients winning and ultimately extorting healthy patients).
Nonetheless, it's certainly an interesting idea and certainly provides something for existing private and potential public providers to measure themselves against.
