The Internet's architecture largely and implicitly assumes full-time connectivity, a notion that is embodied in key networking principles including fate sharing, soft state, and the end-to-end principle. In contrast, efforts to allow for more graceful operation in the presence of forced disconnectedness have recently been undertaken that change the underlying style of networking used by applications to accommodate both host-level and hop-by-hop disconnectedness (e.g., for deep space networks where connectivity depends on orbital mechanics). In this paper, we offer an initial exploration of the architectural constructs required to support selective connectivity, whereby a host can choose whether to be ``connected'' or ``disconnected''. While we keep our notion of selective connectivity general, the driver behind our thinking is to allow hosts to go to sleep to realize energy savings while not sacrificing their standing in the network. Studies show that enabling such sleeping offers large potential energy savings. Specifically, we explore ideas related to assistants, soft state, host-based control, and application primitives.
