Great article...one thing about the 4g..5g evolution is increasing
cooperation in forwarding and relaying signal, bits, packets (shared cell
tower/base station/antennae across provider). So direct,mesh,adhoc stop
just being edge notions, but are all first class part of the architecture
("don't fear the edge"). There is huge tension between this trend, and e2e
security....I have not seen anyone address how to resolve that tension...
