For me it could be the foundation of a modern take on Oberon and Inferno linage of operating systems user experience, given how Go came to be, with mix of Limbo and Oberon-2.

Having the desktop environment, and given Go's stance on dynamic linking (and kind of abandoned plugin package), replace the dynamic behaviours in Oberon and Inferno commands and application extensions, with D-Bus or net/rpc.

However given the state of desktop fragmentation, most likely it wouldn't be worth the effort, only to get the feeling how it could be like.
