This is a neat trick.
First off you and the other person need Kazaa Lite 2.1.0 Build 3. Ok now on to the nitty gritty. Now start the Kazupernode prog on your comp change over your supernode to a specific node (doesnt matter which one just pick one) Then tell your friend to change to that Supernode as well via phone or chat prog i.e. yahoo msn aim. Once thats done and your bith connected to the same super node just type in the name of the file you want and it should come up with it. then just click it and download normally. Then if your friend has more files you want just right click the file while in your download list and click "find more from same user".
However this is a big waste of time if the file is something everyone else has only use this trick if you are downloading a file that you cant really find anywhere else. But it really works and is quite interesting. LOL
Hope this helps in anyway.
