Absolutely, and that's the rub, isn't it? In-band QoS, no matter really whether it's done using an IPv6 3-tuple, or IP-agnostic 5-tuple (without encryption), is ultimately practical only inside walled gardens.

These discussions bring me back to ... ATM. Trying to re-create ATM with IP. But ATM died, in large part, because of this.
