In what way is IM hierarchial? 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.
