Isn't e-mail unreliable and slow enough that we don't really want to make this situation an order of magnitude worse, because now we have to send many smaller notices about a message we have waiting for one or more recipients, and then we have to wait for them to come pick it up? Why not just give everyone in the world an IMAP account on your mail server and make everyone use shared folders? >> Indeed, I'd be interested to know if there is a single analog >> anywhere in the world for this kind of system. > > 1) Lotus Notes. No, not really. Besides, we all know how poorly LAN e-mail packages scale. Been there, done that. > 2) Usenet, with cryptographically protected messages > that can only be read by their intended recipient(s). Again, not really. Nice idea, but the OP said that the messages themselves were never sent, only notices -- the message bodies would then be retrieved via a pull mechanism. -- Brad Knowles, "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -Benjamin Franklin, Historical Review of Pennsylvania.
