If you don't mind, I'm going to try and use Ethereum to fix healthcare in the US. I've got a Dapp I'm working on that will enable the fabled unicorn of hipaa compliant interoperable EHRs. I plan to protect everything with whatever patents are appropriate and then donate to a non-profit to ensure that it actually does stay interoperable. I believe I already have what I need filed. DApp is under way and mining is working out fairly well. Healthcare is antiquated and ready to be fixed, but it's still a massive beast. I think I'll need more help than I currently have. Anyone interested?
