Perhaps not the best possible world, but why not a decentralized model
that is enhanced by (but does not require) a centralized authority? This
seems to work fairly well for a number of existing networks.
If your trusted authority of choice is subjected to legal or technical
DoS attacks you can always fall back to another option:
* durable identifiers that you've already acquired
* an alternate "central" (federated might be a better term) authority
* exchange durable, attack resistant identifiers (eg: content hash) over
existing social channels (email sigs, blogs, IM, SMS, ...)
* keyword (or other) search without trust metrics (at least the network
still works, you just might have a higher signal:noise for certain
