I was really busy today with other things so I wasn't able to work much. I finished reading about the freenet architecture. It shares a lot of similarity with Kademlia DHT in that both use xor to determine an abstract "distance" between nodes and keys and store keys in nodes that have a smaller "distance". Both seem fine, to be honest. I think Kademlia DHT has a slight advantage in that there probably will be less hops on average than freenet, so I think I'll stick with it.
