Google has recently announced the availability of next generation Chrome packaged apps in the Chrome Web Store. These apps are essentially offline apps (by default) that have all the resources they need to run offline, but have received enhancements that give them much more system resources to work with.
The bottom-line here is, that Chrome packaged apps are getting more powerful (and useful), which clearly indicates Google's ambition with the Chrome browser and Chrome OS. Soon you'll be able to use fast and efficient web applications using any operating system, essentially blurring the lines between your browser and your operating system.
If you're interested in trying these apps out for yourself, you'd have to switch to the Chrome developer channel for Windows, or Chrome OS. It's unclear when these powerful apps will be available to the general public, but we'll keep you updated when we find out.
