I agree completely. However, one could equally well say that operations can only be sustained with a revenue stream and trust models among parties that don't already have first-hand relationships can get a tad complicated. Setting up a distributed email environment that supports secure communication among a small circle of friends (especially technically-competent ones) is pretty easy, even easier than the service you posit above. Things become difficult and start to encourage centralized behavior when, e.g., (i) the community allow basic Internet service providers to either prohibit running "servers" or make it unreasonably expensive, (ii) one wants the communications to be persistent enough that storage, backup, and operations becomes a big deal, and/or (iii) one wants on-net or in-band ways to introduce new parties to the group when there are Bad Guys out there (which more or less reinvents the PGP problem). Architecturally, one can make a case that the Internet is much better designed for peer to peer arrangements than for client to Big Centrally-Controlled Server ones, even though trends in recent years run in the latter direction (and I still have trouble telling the fundamental structural differences between a centralized operation with extensive "web services" and users on dumb machines on the one hand and the central computer services operations of my youth on the other). So, a good idea and one that should be, IMO, pursued. But there are a lot of interesting and complex non-technical barriers. best, john
