I really think that a two-tiered QOS system such as the scavenger suggestion is workable if the applications can do the marking. Has anyone done any testing to see if DSCP bits are able to travel unscathed through the public Internet?
Given the bad track record for PMTU 'frag needed' ICMP, ECN, and anybody in 69/8, 70/8, 71/8, I'll make the prediction that DSCP bits are mangled in too many ways to make effective use of them, and we can expect a 3-4 year effort to get stuff cleaned up before it works as intended.
