DHT doesn't seem to be robust or fault-tolerant to me.
How so? The mainline DHT used for torrents has been operating without outages for years, with tens of millions of nodes taking part (with a churn of about 10 million a day). The DHT is self-healing in that if there's a small cluster of nodes that are interconnected with each other but disconnected from the main DHT, a single connection to the main DHT will result in that cluster completely rejoining the main DHT.
I also don't see how it would provide any anonymity as seems to be claimed.
Indeed. The system appears to provide decentralized, encrypted communications. That's a very important aspect to be sure, but it's not anonymous communication. I don't see any mention in the text or links of the summary saying that the system is intended to be anonymous, only encrypted and decentralized.
OTR over TOR might make more sense.
Perhaps. It'd be interesting to see a Tor-based DHT that would allow for this type of chat protocol to be extended -- that would make it both encrypted, decentralized, and anonymous.
