Do you (or if someone on these big nets wants to own up offlist) have pointers to indicate that deployment is significantly different now than they were a couple years ago? Even better, perhaps someone can do a preso at a future meeting on their recent deployment experience? I did one a couple years and I haven't heard of things improving markedly since then, but then I am still recovering from having drunk from that jug of kool-aid. :-) Once you get past the religious debates, DSCP can be very useful to large, complicated networks with many entry and exit points. Think about how large networks use tools such as BGP Communities to manage routing policies across many different types of interconnections. You may want to consider how networks use similar tools such as DSCP to mark packets entering networks from internal, external, source address validated, management, etc interfaces. There are limited code-points so you can't be too clever, but even knowing on the other side of then network that a packet entered the network through a spoofable/non-spoofable network interface may be very useful.
