I was just thinking about this the other day. If I had to build a new OS built on top of a web interface that controlled an operating system, installed programs, opened files with set programs, shared between programs, and made it all cloud based, what would it look like? How could I do that? The front would have a set number of UI concepts, theme, interface commands and controls. The back would have data that would appear in the form of drop downs, item list, buttons, images, colors, etc (i think that covers everything). And then a special renderer would be paired with the interface. This renderer would depict (a VNC?) things like the layout of a webpage (... by firefox?), the structure of a cad drawing, the photoshopping of a 1 GB image, the 10,000 messages in your inbox, all based on the data obtained from the web. I am not too familiar with GPU stuff so I don't know how much the renderer can partially leverage a local GPU versus a cloud GPU.
