Can a Chrome packaged app and a Chrome extension share local data?
===

From what I gather, Chrome apps and Chrome extensions are just two different ways of viewing some basic html/js/css files that have access to certain Chrome APIs.  What I'd like to know is - can you share data between them?  For example, can I do `localStorage.setItem('name', 'john');` in a Chrome app, and have `localStorage.getItem('name');` return `john` in an extension?  If so, how do I link the app and the extension so that this is possible?
