And how do you download? The problem is: Without more servants that accept incoming connections you have to trust on Pushs very often. But Pushs won't work bewteen two firewalled host (or better say bewteen two servants that can not handle incoming connections). When you see current Limewire host statistics [1], only few servants do accept incoming connections and on those the network file transfar relies IMHO.

For sure it's good to find alternative ideas. I didn't get the useful addition to the Superpeer concept, could you explain please? How a bout the "superpong" mentioned in another thread, did you think that's a good idea?
