Usenet has long since demonstrated the ability to route around amazing amounts of damage and flakiness and to maintain communications over very slow (including sneakernet) links. Arguably, that sentence describes the normal operational state of the network on a typical summer day just like this one, 30 years ago. ;-) Usenet has some very nice properties for applications like this: 1. There is no centralization. Thus there is no single target to shut down or block. 2. Messages are not addressed to individuals. This frustrates some traffic analysis. 3. It's transport-agnostic. Messages can be passed via IP, via UUCP, by USB stick, CD, DVD, etc. 4. It's highly delay-tolerant. 5. It's content-agnostic. 6. It's highly fault-tolerant. 7. It doesn't require real-time IP connectivity. In areas where IP connectivity is scarce, expensive, intermittment, wiretapped or blocked, this is a big plus. 8. It's standardized. 9. Mature open-source software already exists for it. 10. Peering relationships can be ad-hoc. Not that it would work for this application as-is: the article duplication method would need to be replaced because the current one leaks origin information. But I think that's a solvable problem. I submitted a proposal on this very point a few months ago; haven't heard a thing back, so my guess is that's not going anywhere. But I think with a relatively modest investment, the additional code could be written and a testbed network constructed to figure out if this really is a viable architecture. My hunch (of course) is "yes" but I'd prefer to remain skeptical until there's some experimental evidence that it'll hold up under the kind of duress we've seen in various countries during the past few years. ---rsk -- Too many emails?
