interesting approach. how does the cost scale for persistent tunnels? durable objects bill by active duration and memory, so this seems expensive compared to a standard ingress controller. curious if you hit any connection limits per object.

since we allow agents to execute arbitrary python, we treat every container as hostile. we've definitely seen logs of agents trying to crawl /proc or hit the k8s metadata api. gvisor intercepts those syscalls so they never actually reach the host kernel.

we run ~10k agent pods on k3s and went with gvisor over microvms purely for density. the memory overhead of a dedicated kernel per tenant just doesn't scale when you're trying to pack thousands of instances onto a few nodes. strict network policies and pid limits cover most of the isolation gaps anyway.
