How does it work if I am encrypting my traffic (independent of
protocol version)? On top of that the diffserv model provides
no control to the originator of the packets, and that is the
source of the money which makes a business model work. Yes there
is a technical definition for diffserv QoS, but there is no
sustainable business and operational model which includes the
source of the packets & money. A strict diffserv network is a
providers fantasy land. There must be a mechanism for the
endpoint to inject intent or there will be no reason to pay.

No, I base my thinking on the fact that for diffserv to work
there has to be a visisble set of immutable bits with well-known
end-to-end semantics. Otherwise each provider can't figure out
which PHB is appropriate.
