| Now you might say, "but I can't download from those three, because others already do. I want to get all addresses from which I can download," (and you are not alone with this. I feel the same). By looking at the Real World, we can find a solution to this problem too, without having to waste too many resources on it. There (in the Real World), if you ask a specialist to explain something to you, and that specialist is busy, he or she will know some other specialists (because they know each other) who might have more time at the moment.
Getting this into Gnutella is not as easy as the Ultrapeer-Leaf Model nor as the Dynamic-Query Model. But the programmers found a way. As I stated at the Dynamic-Query-Model, you will get more than one number where you can ask. Now, when you call someone who should know the answer, you also give him or her the other numbers you know about. That way, the specialists will get to know each other (the same way, as the GWebCaches, which I mentioned before, learn of others of their kind). As everyone who asks also brings his or her own set of numbers, the specialists know more and more additional addresses, and when you ask them to explain, and they don't have time at the moment, they give them to you (they do it even if they have time, just in case they could be interrupted, and because in Gnutella you can download from more than one source at once, just like you can in the overnet-network (which does this to the extreme, but is only really efficient for big files)). Additionally, the specialists also add you to their number of alternate-contacts, as soon as you know enough to teach others.
This is why often many people download files from you which you just downloaded yourself.
