According to Microsoft, using "network coding", Avalanche can re-create missing blocks of data that can be used in place of missing chunks. If this is true in practise then it's another point for reliability of P2P distribution. Microsoft also claims that Avalanche will make it harder for file data to become corrupted. While it is good to see at least one major company try to develop on the idea that P2P distribution is suitable for legitimate content, the damage to filesharing’s reputation has already been done.
BitTorrent sites all around the world have been shut down because the entertainment industry highlighted the sharing of copyrighted material among the users. This is where BitTorrent loses out while compared to a P2P network for example, to share reliably, you need o find a BitTorrent site, which is basically a centralised distribution point for .torrent files that are needed for the sharing. Several attempts have been made at "trackerless" BitTorrent, and appear to be getting better and better as time goes on.
