Scaling P2P for the future

We all use P2P like BitTorrent, but the user experience isn't quite there yet. The current generation of P2P doesn't scale from popular to niche downloads. Often we'll be sat waiting hours or even days for a niche track to download, and likewise my potential for uploading will be left unused as no one needs parts of the tracks I have.

The solution is for the super-nodes to hint the niche files which are struggling to be cached by other nodes, boosting the niche file's availability while the other nodes are otherwise idle; a neat balancing trick. Skype uses similar approaches, diverting firewalled traffic via idle nodes.
