picoGUI: An X Alternative?

bockman writes "While started as a PDA-oriented project, the picoGUI people seem to be implementing many ideas which I think would be good also for a desktop graphics server ( high-level client/server protocol, presentation layer in the server _but_ modular, application management also modular,...). So I wonder: what would it take (apart porting tons of applications) to make it a suitable alternative to X+[your toolkit of choice]+[your window manager of choice]?"
