I have been designing an OS distribution that would work much like you describe. I am thinking about using NanoBSD to build a lightweight FreeBSD core, and running something like CEF/CEFPython to display the UI, all in HTML+CSS+Javascript. Apps would have their very own Jail, and the UI would be basically a browser that would connect and communicate with the front end. Somthing like that, anyway. It is kind of a hobby design at the moment. One of these days I may get waround to putting it all together and releaseing it for others to play with.
