[e2e] new network architecture idea -

pub/sub in the original implementation by tibco et al mapped straight onto multicast 
AND had its own transport (PGM) which was a neat architecture

BUT i am not talking about simply pub-/sub - that was for illustration reasons...

at the end of th day, the receiver has some stuff they are interstd in - you buy
newspaer x, or you tune to tv or radio station y/z OR you subscribe to some 
belief....all of this is *AND should be* receiver interst based, not sender based

even email (I'm not interested in most the spam i get  - this is an indication of a major architectual error
that the cost of an activity for a pasrticipant doesnt match the need - 
and the resource expended isnt paid for by the right party)

packet swarming is a simple idea - you need to buy into some complete changes of 
ways of building net s (you dont send to an address - you percolate traffic to a repository
cloud which intersted parties may pick packets out of  - this works even for 1-1 commnication
(if you send an email to e2e but cc: me, i might see it as i probably "subscribe" to messages
with some field about me - hey, i am sufficiently egomaniacal to want to see stuff like that:)

the technoligy exiwts now to do this at a packet level, not just an application level
