That's what can be deducted from some papers but this is really a 
shortcut, like "the bittorrent network is less secure with the DHT than 
with trackers", funny statement...

I must add some technical faqs following some questions I had but an 
example of a decentralized anonymous p2p system is what I have specified 
in [1], some concepts are new, I don't see it in any paper, the 
peers/content discovery system has several layers, not only the DHT, the 
keys are ephemeral and the nodeIDs are directly related to them, I 
believe this makes really difficult for the attackers to position 
themselves in the network, but since the content is not advertised by 
the peers that have it but by others, while difficult it's probably 
feasible for an attacker that has the possibility to control a large 
part of the space to attract the peers to a fake/evil content.

The system answers a specific constraint coming from WebRTC: the peers 
need to be introduced by a third party, but after the initial bootstrap 
they can introduce themselves directly.

Could some of this apply to the Tor network? Probably, the best way to 
know is just to try it.
