None of this shit works without a correctly configured, working network. In short order that network will have to transport ipv6 as well as legacy ipv4, and ipv4 will - indeed must - go away. There will be acres of physical network plant to organize, manage, upgrade & replace.
Locally hosted apps will be niche apps, for those things which aren't in the cloud yet or that you don't want to put there, e.g. 911 systems, (air) traffic control, anything realtime that can't stand latency, and anything connected to a sick human being.
