There are a few projects working on this. One problem is key management and giving the app a connection to the blockchain. If you do key management in the webapp and read from the blockchain via a centralized API, thats not much of an improvement over existing systems. Ethereum core&#x27;s solution to this is a special browser, but it is still under development. I&#x27;m working on a project[0] that takes this on, but is still a couple months out from a public beta. Its a bit of a hack but it manages a zero-install solution by having a sort of browser-in-browser that intercepts transaction signing requests and provides access to blockchain data. Can&#x27;t wait to get it out there.<p>[0]: <a href="https:&#x2F;&#x2F;metamask.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;metamask.io&#x2F;</a>
