The URL has includes the host's name, so the namespace isn't flat. File are transfered using an end-host multicast tree, but to join the tree a host must connect to the host with the file first. The advantage of this is that each host effectively has its own namespace that cannot be polluted by other hosts. Unlike Freenet, Jungle Monkey does not have searching inherent in its design. Instead, Jungle Monkey has centralized search servers which hosts can optionally use.
Search servers advertise themselves on root channels so that new search servers can be added.
Anyone can run a search server anywhere. Freenet was conceived by Ian Clarke of the University of Edinburgh. The protocol won't be fully documented until version 1.0.0 and may change at any point until then, especially the end-host multicast code. Write us for more information. They are version numbers.
