Well he doesn't seem to be aware of all the ID/Locator split discussions in the IETF (see HIP, LISP, ILNP). Mobile QUIC will give Google even more insight about how users move from network to network.. Mobile IP didn't fail because the latency was too bad. It failed because there was financially viable use case. The mobile providers wanted a purely network-based roaming solution to control the billing model. WiFi vendors couldn't count on OS support of mobile IP, so they went for L2 solutions. Because there were L2 solutions, the OS vendors didn't bother to implement mobile IP.
