Well ignoring security for a minute, I have issues with anything that makes it easier for telecoms to charge for and provide different tiers of service for limited parts of the internet (net neutrality), and as I see it, pushing services towards the edge can't possibly work without some degree of opt in. Then there becomes a fundamental issue with the telecoms wanting things hosted on their nodes for performance, and small scale sites being to little to for the telecoms to care.

This is all still very speculative, but there isn't a telecom out there I'd trust to run my servers.

I agree we could use nice ways to serve content more locally, and there's already some solutions here, but I'm struggling to see how it works as part of a cell network protocol without redefining a lot of how we expect the internet to work.
