It works with torrents fine as I said. Or you are talking about P2P indexing? I think this can be solved. And I said that it can be used together with relays. The issue with "it works well enough" for me is that in case of an attack, relays can be more easily blocked before there is a ready solution. I personally won't be working on this, so i am not criticizing anyone, but in my personal life I am always proactive instead of reactive.
