It still doesn't work. The data you collect on yourself, even if you collect it using standard NGRouting methods, is *not* the same data that other nodes will collect on you. Those other nodes are at a different place in the network than you are. They have to deal with the speed of the link between them and you, and you can't necessarily know what that speed is.(*) Also, even if a given piece of data takes forever for you to find, that may be fine with the requesting node. You may be their last hope. Really, the only one who can determine who best to route to is yourself. Nobody else is in the same spot as you, in the network. (*) Someday, hopefully, Freenet will work with networks less predictable and reliable than TCP. The other facet to this problem is that even if you could compile the very same data as another node, and come to the very same decision about your routing ability as the other node did, you don't know how your performance compares to the other nodes that it knows about. -todd _______________________________________________ Devl mailing list [EMAIL PROTECTED] http://dodo.freenetproject.org/cgi-bin/mailman/listinfo/devl
