This model of desktop can still be immensely useful. All we need to do is support only a few high level protocols. For e.g. twitter-like streams / RSS, simple high level workflows for generic business purposes, and so on. Browsers should necessarily not be supported. Layout options should be fixed, and totally protocol specific. (For e.g. a twitter-like stream can only be displayed in limited ways. )
