What I'm trying to get rid of is the IRC bootstrapping and the hardcoded nodes in the client, they're easy targets. BitTorrent trackers are used to handle several thousands of requests, so they would probably scale well enough. I'm not even talking about using the DHT trackers, but using old fashioned HTTP based trackers. The fact that each bitcoin client would contact the tracker would make it very hard for an attacker to get bootstrapping clients to exclusively connect to his compromised clients. I would say that using a tracker such as OpenBittorrent provides the same advantages as using an IRC channel.
