I know a lot of us has asked for an IPAD/iphone/mobile app for Healthframe to make our records more portable. I also read that you were hoping to be able to partner with an existing mobile application.
Just a thought . . . have you considered the possibility of providing an html based export document? When I was considering another PHR product, there was the option to export the entire medical record as an html file, which you could then open in any browser and click on attachments, visits, the whole works. It was read only, but contained everything in the PHR.
While an app is great, just being able to carry the records and access them from an internet browser (without storing the actual records on the internet, which is why I went with Healthframe) might be a decent temporary solution.
