The integrated solution somehow needs to incorporate device hotplugging (eg USB, PCI), network device events (netlink), userspace reconfiguration (eg X colour depth and resolution) and maybe network infrastructure (external to the machine, probably SLPv2 or similar), and reconfigure kernel and applications to match.
