This is so very true. Decentralisation is the only way to go, IMVHO. And the lower network level we can decentralise, the better.
I like the decentral model. But I wonder about how to affirmatively deny an influx of attacking nodes overtaking the network. It surely cannot be relegated to the simple user? So that seems 'hard' to me. For example, I think Tor may remain centralish rather than pure dhtish for that purpose. But what if the centrality was undertaken anonymously by some voting humans (or their analytic nodes). Their track recourd could certainly be public yet anonymous therein. You would at that point be trusting/subscribing their record, purely, as opposed to dht or some other means, purely. What would p2p-hackers@ have to say on this?
