What if clients do not need to change addresses? In 2 words: Route /128s. Two ways to do it: - have clients talk stub RP + stub HNCP, be done with it - have first-hop router do proxying for them by advertising the /128s only when they are connected to it (may have issues with e.g. clients assuming /64, but nothing a redirect could not fix, hopefully) This L3(ish) solution actually works for all apps, unlike L4+ solutions some people advocated.
