I realize Gnutella's entire concepts relies on public IPs, but if more people get their ISPs shut down, word will spead and people will quickly migrate to one of the secure apps, such as Freenet, filetopia, etc. I personally am very fond of my Gnutella apps and don't want to see this happen. This is why I warn the developers to somehow take some measures in this area or else Gnutella may not be here in a year or so. I'm not a programmer, so I don't know of the difficulties this may create. But somehow, regardless of the difficulties, Gnutella needs to evolve security without centralization or else it is doomed.
