@nathand I was kind of thinking more of a pirate network: everybody has their own node, no centralized ownership. Keeping nodes up-to-date (and not compromised) is a problem, of course, since you'd have a ton of naive "sysadmins" and the likely point-of-failure would be the distro from which one would update nodes (especially if you are updating the network *from* itself, where a mitm would probably be an issue. Wouldn't want the whole thing to be turned into a botnet.)
