This is why I was hoping the startup MightyApp would succeed. Then it would be practical to build web apps that operated on GB/TB of data in a single tab. Most of the time people would use their normal browser, but for big data jobs you would use your Mighty browser with persistence and unlimited RAM streamed from the cloud. A path to get the best of web apps with the power of native apps. Glad they gave it a shot. Definitely was an idea worth trying.
