Thanks for sharing this! I'm not particularly interested in undertaking a project around this topic..but for the heck of it, glanced at the above link...and happened upon the statement on open source (https://www.commonhealth.org/developers#dev-link-2)...and was glad to have seen it! Now, having read that and CommonHealth's objective...i'm actually intrigued and may play around a bit. Kudos for working on/with CommonHealth!
