The commercial IM systems have a star topology with a tightly controlled core and basically no inter-domain federation, so I don't know why you claim they are hierarchial. Jabber/XMPP has a mesh-of-stars topology which is the same as email's modulo some simplifications (mainly owing to the lack of forwarding). ISTR that you were arguing in favour of a chain-of-trust system for email back in November on the IETF list. I pointed out that the architecture you are proposing is essentially the same as inter-domain routing (IP & BGP) and Usenet, and you failed to explain how your ideas would solve the unwanted traffic problem for email given that the same architecture doesn't solve the unwanted traffic problem for IP or NNTP. http://www1.ietf.org/mail-archive/web/ietf/current/msg44467.html Tony. -- f.a.n.finch <[email protected]> http://dotat.at/ HUMBER THAMES DOVER WIGHT PORTLAND: SOUTHERLY 4 OR 5, OCCASIONALLY 6 IN PORTLAND.
