The way I see it, Piper is much more analagous to a web browser than to a file trader. Just as the overwhelming majority of people who browse the web will not have any original HTML or image files on their hard drive, the majority of Piper users will not have public, useful XML data that they (or others) would care to share. However, piper content repositories (servers) may behave amongst themselves more similarly to file trading systems such as Freenet, or Gnutella proxies with cacheing/aggregation, or napster for that matter. Designing the system so that casual, dial-up users are treated as equally viable sources for XML as persistant repositories is a mistake, in my view. Further, non-persistant connections are useless repositories if the information does not behave in a freenet-style, demand mobile manner. Freenet behavior allows highly demanded content from non-persistant connections to travel to persistant repositories, where it will be more reliably accessable. What sorts of data files do you think will be highly demanded of Piper users across the internet? I can't think of any which is not time-dependent (news, weather, stock, etc.) which must come from a maintained server. All of my other examples are of purely local interest (internal company, family, etc.). -Steve -----Original Message----- From: J.W.

I think we reached a general concensus (at least among the founders of the Piper project) that decentralization was the way to go. So, it is interesting to read about some of the "problems" with Gnutella. Is the discussion moot? And, as usual, there are SOME good comments about this on Slashdot: http://slashdot.org/articles/00/11/22/1432219.shtml Cheers.
