[erlang-questions] Rough thought on a P2P package distribution model for Erlang
Fri Sep 16 20:51:40 CEST 2011
How is this different from the already-solved problem of peer-to-peer
authenticated file distribution?
Tracker-based systems like bittorrent, and fully peer-to-peer systems like
freenet have been around for a very long time, and solve all of those
problems, with different trade-offs for performance, security,
Americans might object: there is no way we would sacrifice our living
standards for the benefit of people in the rest of the world. Nevertheless,
whether we get there willingly or not, we shall soon have lower consumption
rates, because our present rates are unsustainable.
